It’s not entirely clear but there seems to be some shader-related issues. Could you try experimenting with the solutions here?:

I have the same error. And I looked at your logs, I have Ryzen 9 7950X and RX 7900 xtx too. Maybe it’s something to do with this combination :thinking:
But I am not crashing every mission, sometimes I can play 2-3 missions without crashes, sometimes I am getting 2-3 crashes in 1 mission.
And I use Linux btw

I think I fixed it! Played 6 matches today and no crashes.
I did these things, not sure that exactly helped, probably shader cache

  • Enabled Steam overlay
  • Cleared shader cache
  • Removed slight undervolting on GPU

Seems like deleting the cache helped fixing the issue for the moment. Thank you!

That’s great! After clearing shader cache I only had 2 crashes, same error message, but probably some other issue, but it’s a lot more playable than before.
Also I have a theory, that shader cache degrade overtime, because I didn’t have any issues before and suddenly crashes started to happen. So I will try to regularly clear it.

Maybe this link should include steps to clear shader cache
