ProtonDB has a lot of reports of people having the same issue (all with AMD cards), and most not being able to run the game at all with the RADV drivers. I've been able to play just fine with RADV drivers however. I don't have AMDVLK even installed though, so that might be the difference?

i dont have vlk installed either and im running endeavour os with the latest packages installed, the only difference im seeing is that your running a wm while im running kde plasma 5.27.10 and i have tried both kwin x11 and kwin wayland with the same results of it crashing when entering the intro of creating a game
enshrouded.log
here is the enshrouded crash log aswell
thats odd the game is working on kde neon unstable with flatpak steam
edit: if i set reflections to quality the game will crash, setting everything to normal/balanced doesnt make the game crash and its working on endeavour os now so yay :)
On a fully-updated EndeavourOS, with the following stats (and skipping Steam's shader precaching):
GPU: AMD Radeon RX 6650 XT
CPU: AMD Ryzen 5 1600 x12
DE: Gnome 45.3
Kernel: Linux 6.7.1-arch1-1
GPU Driver: amdgpu
Proton: 8.0-5
The game starts and appears to preprocess the shaders.
However, the problems start once the Keen logo shows up, followed by the main menu.
Under X11, when the window is not selected, the game is choppy, but appears correctly (which seems to be expected behavior from my memory of playing on Windows). When I mouse over the window, or click on the window to make it active, though, the window turns black. I can click a menu element (Play or Settings, for example) a frame or two before it goes black, but if I then make the window unselected to see the current state, it will appear back at the main menu. This is the same in either Windowed mode or Fullscreen mode (toggled with Alt+Enter).
Under Wayland instead, it's the same as X11 under windowed mode. However, if I switch in fullscreen mode with Alt+Enter, then the game wholly appears correctly, regardless of if the window is active or not. I still get a black screen game crash when attempting to load a world, though - about 6 seconds after the loading screen starts, my GPU hangs, first evidenced by my inability to scroll a web browser on my other screen, after which my mouse cursor also stalls.
About 12 seconds after that starts, the game crashes.
The crash log is as follows:
https://gist.github.com/SolarLune/205f98300b60908ad06f206999320bc6
I tried a few times more - setting the graphics quality settings to Max Performance didn't help; it still hung the GPU driver. Changing it from my desktop resolution (1440p) to 720p and turning off FSR2 as antialiasing didn't help either - it hung for a longer period of time this time, and then crashed Wayland (I presume) and kicked me out to the login prompt.

I was able to start a single player game running Proton Experimental: Bleeding Edge.
I also had to turn off a particular graphical setting regarding some voxel rendering option in order to have normal frames, otherwise it would render less than 1 FPS.
I do still get an crash of the display driver / display environment if I attempt to join a dedicated server.
Replying to https://github.com/ValveSoftware/Proton/issues/7442#issuecomment-1910828896
That seems to be the same problem for me, hosting works tho
Made mesa issue for the hang when entering a world https://gitlab.freedesktop.org/mesa/mesa/-/issues/10500
Edit: reworded as it likely isn't the intro video or entering the world for the first time part that is the cause.
FWIW, I updated to a kernel-vanilla/stable 6.7.1 from Fedora copr, and the bad behavior changed.
I can now connect to dedicated servers and play mostly normally, and Voxel Detail Models can be enabled now without killing frames.
Point Light Shadows are now broken though, and cause really low frames if enabled.
Otherwise, runs great.
Worth noting that there were several hotfixes targeting the game today. I don't know if any of those would have had a direct effect on our issues.
Back with another finding. As per ProtonDB, starting the game and loading into a single-player world works if I have the RADV drivers installed. On EndeavourOS / Arch, this is done through installing vulkan-radeon and vulkan-icd-loader, I believe, and then running the game with the command VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/radeon_icd.x86_64.json:/usr/share/vulkan/icd.d/radeon_icd.i686.json %command%.
Also note that the game runs fine on Steam Deck at about 25-30 FPS on all Performance settings.
I'm also having similar problems, the game launches fine but when I join a multiplayer game it starts to load then I get a black screen, then loading screen again and after that the whole system hangs and I have to pull the power to restart computer.
I have also found a way to circumvent this hang, if I start a single player game first and then quit to start screen I am able to join a multiplayer game without the system hanging. Doing it this way I loose about 2/3 of my fps though. going from 60-100 to 19-25, mangohud is telling me my GPUs memory frequency is going down from a locked 1000Mhz in the single player game to a fluctuating 400-600Mhz during multiplayer.
System:
Nobara 39
Mesa 23.3.3
Kernel 6.7.0
Proton, its the same behavior with proton 8, experimental and ge-proton-8-30
The game runs fine on Ubuntu 23.10 with a RTX 3080 and Ryzen 7 5700X, even at some times beating Windows 11 performance on the same machine.
However the only glitch I have found is that sometimes when launching the game, it will launch in windowed rather than full screen, but this can be easily fixed by toggling in game.
Whether this is the game, Proton or Gnome is anyone's guess.
I have similar issues. In order to be able to join a multiplayer dedicated server, i need to sett my settings to "Max Performance". When in game again, i turn them on one by one.
The following options causes issues for me:
I can have all other settings on max without issues.
System:
Kubuntu on kernel 6.7.6
AMD 7800X3D
Sapphire RX 7900XTX Nitro+
64Gig 6000mhz memory
Edit:
It seems with those 4 settings disabled, I am able to launch the game as is. The strange thing is that sometimes i can enable some of the settings without it crashing. But not always. But i have steadily played with these off now for a two weeks and no more crashes.
Edit 2:
I can also reliably launch the game with Voxel detail models set to max now. It crashes very rarely with this setting on.
Still not possible to launch with the above 3 settings on anything than low/off.
The game feels very stuttery for me on Wayland as VRR is not being used even when forced to always on in Plasma settings. The game only has windowed or borderless mode and trying it in windowed mode then using KWin to fullscreen it (which enables VRR with every other program, you can tell by slight flickering) does not work for Enshrouded.
with the newest patch it crashes a couple of times when trying to load the shader cache and trying to load into a world will stay in the loading screen for a couple of minutes then it kicks you back out to the menu, also some images are broken
this was under latest proton experimental(bleeding edge)
rx 6700 mesa 24.0.3 kernel 6.8
EDIT: latest proton experimental(bleeding edge) the game is now working properly, able to load in and main menu looks correct!
Can confirm, the remaining issue is the never ending 'validation' of around 10GB. Any known fix for this?

Yeah I am getting the same issue. 9.2 GB of data is being downloaded every time. I have a feeling it is due to the shader cache.
EDIT: Yeah I left Steam to finish processing the shaders in the background and now I no longer get the 9.2 GB download.
EDIT 2: Nvm, it still seems to trigger big downloads but only after a day or so. Doesn't happen with every launch of Steam.
Another issue I am experiencing is if I set Texture settings to Max Quality, all the textures appear black. If I drop it down by one to Quality, it seems okay.
Hello @urbenlegend, please add PROTON_LOG=1 %command% to the game's launch options and attach the generated $HOME/steam-$APPID.log to this issue report as a file. (Proton logs compress well if needed.) Also, please copy the contents of Steam Runtime Diagnostics from Steam (Steam -> Help -> Steam Runtime Diagnostics) and put it in a gist, then include a link to the gist in this issue report.
@kisak-valve Here's the proton logs: steam-1203620.log
To generate these logs, I booted into the game, set the texture quality from Quality to Max Quality to trigger the black texture bug, and then loaded into my world. After spinning the camera around for a few seconds, I immediately quit the game.
Here are my Steam Runtime Diagnostics
For anyone curious, this is what it looks like in game:

Thank you for reporting this issue. I was able to determine this is an NVIDIA driver regression only present in r555. A fix will be shipped in a future driver release. If you wish to reference this bug in the future it is being tracked internally with bug number 4675675.
with the latest enshrouded update the studio improved steamdeck support and added fsr3 which is working perfectly under proton experimental(bleeding edge)
the game also doesnt crash or freeze when switching around graphics settings so there are no more problems that i am seeing now, this under my rx 6700, mesa 24.1.4, kernel 6.10, cachy os
As of last week something broke when running the enshrouded gameserver in proton, should this be tracked here as well? See https://github.com/ValveSoftware/Proton/issues/7995 (it does not appear to be limited to Fedora) and the linked ticket to find some additional testing.
FWIW, I use ProtonGE 9.10-9.12 on my desktop, I use Nvidia 555 on Fedora 40 Workstation (GNOME) and the actual game works just fine.
Steam (native)
ProtonGE 9.12
but yes, the enshrouded dedicated server in a container with proton is broken.
One out of two of my steam deck crashes even tho they mirror each other for settings

Describe what you expected should happen and what did happen.
I use kernel 6.6.3, mesa 23.3.0 and amd fury r9 card and the game crashes after 1 minute with proton 9.03, the system is frozen and reset is needed. I also used proton experimental, ge-20 and got even more crashes. Many steam games work very stable with my configuration. I even do not remember such dreadful crashes with them. They were maybe 5 years ago. Now if a game starts running it continues to work in my system. Thus, crashes are a huge problem of this game.

Please provide logs with the crash if you can
By doing PROTON_LOG=1 %command% as your launch command, it will output a file in your home directory to upload here
You can also use something like qjournalctl to look at your last boot log and it should show what error made that happen

Hello @pwasiewi, the version of mesa you're using is too old to have https://gitlab.freedesktop.org/mesa/mesa/-/commit/79cb8842753e6dc7c10d6c5af1f1cf7ece5ecc75 included. Run the game with the launch options set to RADV_DEBUG=zerovram %command%.
Updated mesa with launch option: PROTON_LOG=1 RADV_DEBUG=zerovram %command% and the same crash with log:
steam-1203620.log
@pwasiewi You said you used kernel 6.6.3, but in your logs it says you're on 6.11.3-zen1. There's a kernel bug introduced in 6.10 which breaks the zerovram workaround (as described here: https://gitlab.freedesktop.org/drm/amd/-/issues/3812), so that could be why it still crashed for you with RADV_DEBUG=zerovram.
I tested Mesa 24.2.7 (and later 24.3.1) on kernels before and after the regression with RX 6650 XT to make sure it wasn't a new type of hang. I got four hangs with the newer kernel in four hours total, and none with the older kernel in three hours total. My repro rate wasn't great, but I would've expected at least one hang in the time I tested on the older kernel if it was a new/separate issue, so it seems likely that this is the same issue as before.
Until there's a fix for the kernel bug, the game should be fine on a 6.6 kernel (with Mesa 24.0.8 or newer, or RADV_DEBUG=zerovram).

This is a native vulkan game and there is no graphic api translation happening in proton. This is almost assuredly a Intel driver bug and should be reported to Mesa.
Hello @zottelmann, if possible, please retest with a current build of mesa from a PPA like kisak-mesa, and if it continues to misrender, then report your findings to your video driver vendor.
Possibly related to https://gitlab.freedesktop.org/mesa/mesa/-/issues/12387.

It doesn't happens on every play, but only when loading a save. I have included a trace but umr logs are empty, probably because the gpu resets before it could take a trace.

Not sure if this is a proton issue, but noticed the fossilize replay taking ages for this game (also saw people mentioning in reviews that shader precaching was taking a long time).
Noticed that the shadercache file is enormous:

Seems it includes the entire shader hlsl source code a couple of times. Probably an issue with the game, but maybe something that could be more efficient in proton too or going wrong? Not too familiar with this stuff.

Linux/AMD workaround for Enshrouded not launching: jemalloc fix
Posting this because I just spent an embarrassing amount of hours debugging this and I don't want anyone else to go through the same thing.
I'm on Linux with a 7900 XTX running Enshrouded through Proton. Game was working totally fine for almost 3 hours, had a crash mid-session, and after that it just refused to launch. Hit Play, it thinks for a few seconds, then the button goes back to green. No error window, no crash popup, just... nothing.
I tried everything:
None of it worked.
What actually fixed it: swapping the memory allocator to jemalloc.
How to tell if you have the same problem
Set your launch options to this and try launching once:
PROTON_LOG=1 RADV_PERFTEST=gpl %command%
Let it fail, then check ~/steam-1203620.log and search for:
malloc(): unaligned tcache chunk detected
If that line is in there, you're probably dealing with the same thing.
Your game log (enshrouded.log in the game directory) will cut off somewhere around Vulkan device setup, usually near a line about DLSS.
The fix
Install jemalloc for your distro:
sudo pacman -S jemallocsudo dnf install jemallocsudo apt install libjemalloc2Find where libjemalloc.so ended up:
find /usr -name "libjemalloc.so*" 2>/dev/null
Then set your Enshrouded launch options to:
LD_PRELOAD=/path/to/libjemalloc.so RADV_PERFTEST=gpl %command%
For Arch that's usually:
LD_PRELOAD=/usr/lib/libjemalloc.so RADV_PERFTEST=gpl %command%
For Fedora:
LD_PRELOAD=/usr/lib64/libjemalloc.so RADV_PERFTEST=gpl %command%
Why this works (best I can tell)
Enshrouded ships with NvLowLatencyVk.dll, which is NVIDIA's Reflex Vulkan layer. On AMD hardware under Proton, this DLL still loads and hooks into Vulkan initialization even though it doesn't do anything useful. During Vulkan startup, Wine's vulkan-1.dll goes through an unload/reload cycle, and the Reflex hooks seem to cause some heap corruption in that process. glibc catches it and kills the process before the game ever gets to the menu.
With jemalloc handling memory allocation instead, the game gets past that init sequence, properly detects "non-Nvidia GPU," skips DLSS, creates the Vulkan device, and runs normally. I played for a few hours after applying this with zero issues. jemalloc is used by Firefox, Redis, and a bunch of other production software so it's not some sketchy hack.
I want to be clear, I'm not 100% certain this is the definitive root cause. But I am certain that this is the workaround that got it running after testing literally every other option. The malloc tcache error is consistent and reproducible, and jemalloc consistently gets past it.
Note for the devs if you see this
The game already correctly detects non-NVIDIA GPUs later in init (there's a log line that says "Skipping DLSS on non-Nvidia GPU.") If that vendor check happened earlier and prevented NvLowLatencyVk.dll from initializing its Vulkan hooks on AMD hardware, this whole class of crash probably goes away for Linux AMD users. Making the Reflex DLL a soft dependency or gating its load behind a GPU vendor check would be a clean fix.
Also worth noting: once you're in game on AMD, set NVIDIA Reflex to Off in the settings. It does nothing on AMD hardware and it's tied to the DLL that causes the problem in the first place.
Setup for reference
AMD Ryzen 9 / RX 7900 XTX / Mesa RADV 26.x / kernel 6.12 LTS / tested across GE-Proton, Proton Experimental, Proton Hotfix, Proton 9.0-4, and Proton 10.0-4. All same crash, all fixed by jemalloc.
Hope this helps somebody. If you see that malloc tcache line in your Proton log, give jemalloc a shot before you pull your hair out.
