Steam Game Constantly Crashes to Desktop (CTD)

Game crashes to desktop (CDT) at random, brief intervals. I restart Steam and verify files, but this does not resolve the issue. This started with the Winter Update. The game has been stable prior to that.

I am running on Linux (Nobara 40) with 64GB of RAM. This occurs under both Wayland and X11.

I have used GE-Proton9-20, and 9-21, as well as Proton Experimental.

Nightingale runs fine on my Steamdeck, though at much lower graphics quality.
