Try turning off cross- saves and test if that fixes it... Having only one save point means you are open to permission issues as well as networking ones so it narrows it down
I tried this and sadly it didn't work.
But, after a few hours of testing I tried: limiting the FPS to 60 and ran the game in fake Fullscreen. The game seems to function properly without crashing. I also ensured that I added bg3 to my exclusion in Windows Security.
thanks for the support.
