I believe to be experiencing the exact same issue on gentoo using flatpak. A quick debugging showed me a NULL pointer dereference in vfprintf after a call to wrapper_fopen (i believe that is the function name) to open ~/.steam/steam.token

@b1tbrusher What did you use for your debugging? I wanted to investigate the issue further on my system but I didn't know how to read the core dumps.

I used IDA freeware to debug the steam client

@b1tbrusher Thanks, I'll check it out.

Having this issue too, with a flatpak on chimera linux, however it works fine using wayland and segfaults on xorg.

@i-just-lizard your log reports that 32 bit GL drivers are not working, and complains about various dependencies that may be missing from your slackware install. That might be a good starting point.

I am facing the same issue with a very similar context (Slackware-current, CPU AMD 5600x, GPU AMD RX6600xt, kernel 6.6.4 or 6.7-rc4)

Exact same issue with Steam either from Conty, Flatpak or local-with-multilib.

Same log

I also get the same error on 2 laptops with intel IGP where it fails to load iris instead of radeonsi

Same errors about missing or broken 32 bit GL drivers.

The users with non-nvidia related drivers may have a different issue than the original poster.
For Mesa issues: I had rolled back two updates that were applied and was able to start Steam again on Linux Mint 21.2 using Steam flatpak (using timeshift as the previous version wasn't available in the PPA):
23.2.1-kisak2-j to 23.3.0~kisak1~j from the kisak-mesa PPA and org.freedesktop.Platform 23.08.7 flatpak

Today there was a new org.freedesktop.Platform 23.08.8 update that also brought in a matching 23.3.0 org.freedesktop.Platform.GL32.default.

You may want to try again after checking updates.

For nvidia or mesa, if steam is logging libGL errors before crashing it may be missing or have a mismatch of GL drivers:
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: radeonsi
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast

I'm sure it used to log another line complaining it could not load a compatible GL driver.

@i-just-lizard your log reports that 32 bit GL drivers are not working, and complains about various dependencies that may be missing from your slackware install. That might be a good starting point.

Other software works fine, for some reason, I rollback system a bit, it's working for now..
But yeah, good starting point, will try different things on parallel install.

Replying to https://github.com/ValveSoftware/steam-for-linux/issues/10263#issuecomment-1840817544

I'm sorry to post this off-topic request but could you detail how you went back to a working setup?

EDIT: Can confirm this doesn't happens under Wayland.

I had the same issue on a fully up-to-date slackware64-current multilib (didn't try a clean install). As @TTimo and parts of the log output suggests, this is due to 32bit mesa issues; the -current multilib is a bit behind -current at the moment:

# ls /var/log/packages/mesa-*
/var/log/packages/mesa-23.3.0-x86_64-1  /var/log/packages/mesa-compat32-23.2.1-x86_64-1compat32

I fixed it by manually creating a compat32 version of mesa 23.3.0 from my local slackware-current (32bit that is) mirror with convertpkg-compat32 (full command: convertpkg-compat32 -i mesa*t?z -d ~/tmp/) and upgrading to that so both the 32 and 64bit packages now have the same version again:

# ls /var/log/packages/mesa-*
/var/log/packages/mesa-23.3.0-x86_64-1  /var/log/packages/mesa-compat32-23.3.0-x86_64-1compat32

The crash is occurring inside the debugger section of the script. The console does not provide any further information other than that the execution ended on line 798 of the script with a segmentation fault.

Thanks, I appreciate your suggestions. After upgrading to Ubuntu 24.04.1, the issue with Steam has been resolved and the software no longer crashes on launch.
