@amrits, for what it’s worth and in case you haven’t noticed them yourself already, there are a few reports in the Proton issue tracker that could perhaps be helpful with the debugging:
- reverting to 510.108.03 might be solving the Xid 31 crashes
- a hypothesis was put forward that the problem might be related to DLSS (as 510.108.03 doesn’t support it)
- for some people at least the crash is 100% reproducible when receiving “phone calls” in Cyberpunk
- other people have mentioned that while they don’t get crashes (but using 535.104.05, not 510.108.03), the same in-game “calls” tank their performance really hard for inexplicable reason

Thank you very much for your hard work on this and the other issues with the driver.
