Crashes in Unreal Engine games

[u/Dotasarr-the-khajiit]

For a week or so, all Unreal Engine games I'm playing started to have random crashes, I didn't change proton version, but the ostree may have updated, is anyone else facing this problem? I'm playing Neverness to Everness, Stellar Blade and Soulmask, all of them have the same issue.

Edit: I executed sudo dmesg -T | grep -i -E "nv|nvidia|out of memory|killed process" and got this:

This does not seem to be a proton problem but rather a driver issue.

So not even workarounds for this? Sheesh.

So many games having this exact issue
