System Freeze/Crash in some games

I've started having an issue where my system will completely freeze after a game has been running for a few hours. The screen stops updating and the system stops responding to input. Game audio and audio from other applications continues to play. This requires a full reboot to fix. This has now happened a few times in the last few weeks with multiple different games.

Specs:
  • CPU: AMD Ryzen 7 1700, 8 cores
  • GPU: Nvidia GTX 1070 w/ 555.58.02 Driver
  • Bazzite 40.20240801.0
  • Using KDE 6.1.3 and Wayland
  • Default Proton settings in Steam and Lutris
The journalctl -b-1 output at the time of the freeze (War Thunder running from Steam with Proton and Gamescope, freeze at 19:57):

One from several days ago that had a little more info (Division 2 running through Ubisoft Connect on Lutris, freeze at 20:17):
