D4 on Steam freezes since last update 1/2024

I'm on OpenSUSE Tumbleweed. Latest NVidia proprietary drivers on 1080Ti. Proton 8-4 crashes faster than Expiremental, but both still consistently crash.

Everything was working perfectly until recent D4 update. Now game freezes after 1-2 minutes in game.

GPU VRAM is not exhausted. CPU is mostly idle. Plenty of RAM.

Doesn't seem to be caused by anything specific. Will freeze whether I'm in a fight or in a town.

Anyone else experienced similar issues? Not sure how to debug this, but I can't play anymore and it sucks.
