Working on getting logs, the game is open now. I am just waiting for it to freeze again. Sorry about that should have thought of it before posting. I turned screen locking and sleep mode off so idk if that would be it.

EDIT: Actually I think you may be on to something. This is the longest the game has lasted. I did actually have screen locking and sleep mode on! I had these crashes on my original cachy install where I had it off. I then installed windows to test and I also updated my motherboard bios. The game ran fine in windows (even better because the dx12 bug was not present). So I wanted to give cachy a go again, I then reinstalled it and ran the game again and left my pc. My previous install of cachy I for sure had screen lock and sleep off.

This install I forgot, when I left the pc the game had froze again and then I posted. This time I turned it off and the game is approaching 2 hours! So I think my motherboard was unstable because of expo profiles before the bios update, The bios update fixed the previous crashes, and now the crash before this post was because of screen lock/sleep. I am gonna let it run another half hour with different settings just to make sure.

Did you use the -nolauncher launch option?

ProtonGE 10-28 is the proton I am using. I have tried proton experimental and 10-03 no dice 😕
