First off, I have the GoG version, so that's why I'm not flagged as an owner...
Secondly, my specs:

WIN 10 PRO 64 21H2
64 GB DDR4 GSKILL
AMD RYZEN 9 3900x
RTX 3090
SAMSUNG QVO 2 TB SSD
WD BLACK 7200 RPM HDD 1 TB (The drive it's installed on)

The game was working fine a week or so ago, yet all of a sudden I get this error[i.imgur.com] when I try and load a world...

I'll do a rollback on the last patch just to be sure, but the crazy thing is that once I reinstall the game it works fine for a few startups, then wham, back to the crashes, I really love this game and would love to have a fix for this issue!
