Roll back Nvidia Drivers to Nvidia 572.60, Nvidia absolutely broke something in 30XX series cards drivers trying to fix the mess they have in thier 50XX series GPUS.
See this thread, im not reposting all the steps I went through trying to figure this out. Good solid two weeks of crashing like clockwork in M+ content. Use DDU to clean out all of Nvidias drivers, and go through the thread for more information.
