Hello @iron217, 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/8616#issuecomment-5571400841.

Your system information
SteamOS 3.10 Build: 20260827.1000(SteamRT3 build)
Please describe your issue in as much detail as possible:
In the previous update, with a different kernel but roughly the same Mesa version, I played for 80+ hours without any app crashes or freezes — just playing the game, and the screen might freeze after 10 minutes, or it might freeze after a couple of hours. Proton log is not related to this session, the game never froze with logging.
