@kisak-valve I've been able to reproduce the issue today with 5.13, but switching to 6.3, I have not been able to reproduce the issue in a few hours of play time. As such, I dare to conclude that with 6.3, this bug is fixed.
Sadly, I think I have found another bug, related to device inputs. In both Quake Champions, as during my tests with Amid Evil, I noticed an input lag that occurred after some time of playing. I'll log a separate issue for that:
Spoke to soon. Here is logging of the issue occuring with 6.3-1:

I confirm:
Symptoms
Hard crashes at random moments. Sometimes within minutes, at best after twenty minutes.

Reproduction
No clear indicator. My first instinct is that it's graphics related, and turning post-processing effects to low does seem to resolve the issue.
