Hello @chknatwork, a logged message like 00c8:err:xrandr:xrandr14_get_adapters Failed to get adapters is something you'd see coming out of Proton instead of a Linux native game port. Looking at your compat_log.txt, it looks like you've configured Steam to run the game with some version of Proton GE.
We're tracking issues with games run with Proton in the Proton issue tracker. Also, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/4061#issuecomment-1636768334.
As a side note, if you have issues with the Linux native variant of the game after reconfiguring Steam, then that should be reported to the game's dev(s) instead of here.
