so I managed to somehow fixed the crashing not 100% sure what did the job though
-cleaned my pc from dust
-reapplied thermal paste on a cpu
-reinstalled fresh gpu drivers
-cleaned game cache
-freed up space on an ssd where bg3 is installed
-changed paging file to auto
-scanned for system file for errors
-undervolted my cpu and gpu
-disabled xmp mode on ram
I think the actual thing that helped was getting more space on an ssd though
