Additional Perspective on the 0x80000003 error: I’m able to replicate the error when I run the game on an Intel GPU (Intel UHD Graphics 620, 128MB display memory) even when I bring the graphical settings all the way down to 320x240 with everything on low. This could suggest that the error is a result of the graphics card unable to handle the graphical intensity of certain maps (Isle of Sgail is susceptible to these crashes, sometimes before the level even loads).
I also noted that, for Mumbai at least, the game crashing that occurs right after saves tends to occur if I make saves after killing lots of civilians. It seems that, for Mumbai at least, the bodies of killed civilians do not despawn, and loading the save will crash the game. Civilians also don’t run away and despawn (unlike the protest crowd in Marrakesh). Thus the GPU may be unable to handle the save loading.
I will see if DX12 has any effect on the rate of crashes for an Intel GPU.
