Ive been having the same issue and the only way ive managed to delay or temporally stop the crash is to go into Nvidia control panel click on the help tab and turn on debug mode for some reason it helps but i still tend to crash just not as frequent. Bungie hasnt been able to help me at all with this issue and havent found a thing anywhere else on the internet of the forums we are all just waiting for bungie to fix it. some think its to do with overclocking the gpu or memory leak bug or something like that. Im even using a 2080 ti with a 9900k and i wasnt getting it on my old 1070 so not sure what up with that
