"FIXED" Entire computer occasionally crashing when loading a new instance

My entire computer would occaionally crash on the loading screen when entering a new instance (every 20-30 instances). It would not just crash the program but my entire pc, forcing me to shut it off using the power switch.

I turned off Engine (cpu) Multithreading and this "fixed" it. 0 Crashes for days so far with this option disabled.

Now the issue is my framerate suffers on high density maps. Hope GGG can fix this soon.
