Game crashes when trying to launch, doesn't reach the menu before it crashes
I've tried proton cachyos, GE latest, experimental, 9.0.4.

Reproduction

launch the game

Xxpander69 2025-08-15 github

works after
WINEPREFIX=/mnt/SSDGames/SteamLibrary/steamapps/compatdata/961200/pfx wine '/mnt/SSDGames/SteamLibrary/steamapps/common/Predecessor/Engine/Extras/Redist/en-us/UEPrereqSetup_x64.exe'

ofc change the paths accordingly.
seems it just doesnt install UE pre-requisites

I've tried this, replaced /mnt/SSDGames with the path in which steam is installed and the game doesn't launch at all. Idk maybe I'm missing something.

You have either different issue or something wrong then.
you can also just install 64bit vcrun2022 to fix the issue:
https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170

try cleaning the prefix maybe, steam installs vcrun2019 by default but game requires vcrun2022 also.

edit: or you can try protontricks 961200 vcrun2022
havent tested that method myself though

THX ALOT. That solved the problem. Just installed vcrun2022 through Protontricks and Predecessor runs great again.

Confirming as well, using protontricks 961200 vcrun2022 solved the problem 👍
Thank you very much!

This doesn't occur anymore (I'm using CachyOS/Gnome) and also using protontricks 961200 vcrun2022 as mentioned by @xpander69 works, but I have a different issue and it's reported here: https://github.com/ValveSoftware/Proton/issues/9345
