Symptoms

Worked perfectly until 2-3 months ago, been fighting crashes ever since.
I can play the game, anywhere from 10s to hours, recently no longer then 10min, eventually helldivers 2 will crash. Steam client, OBS (if running) will also crash and it will often freeze my WM (KDE)

If I begin to play the game again without first restarting my PC, the terrain will be full of tiny holes that cause my character to fall and glitch out:

I have asked arrowhead support, but they just blame proton and ghost me.
