NO, I don't blame the game, more likely something running while you play it or it could be the game uses parts of ram not normally used
if ram tests out OK, what WIndows classifies as memory is also storage drives so what hdd do you have?
try running driver verifier again. It should tell us if its another driver, none stand out like last time. Its possible we missed one since you get same error in same game. Not all new drivers are perfect, they just stand out less than say old ones do. No scarlet crush this time (yay)... oldest drivers are from 2017
win 10 runs certain processes only when its idle, so it could have been doing any number of things like indexing hdd, defragging drives, and several others I can't think of right now. So its unclear what might be cause of idle crashes, especially without the dumps
