Hey, Oceanmaster!
This is the DX12 Nvidia TDR crash we are currently tracking. Go ahead and change your graphics API to DX11 and the crashes should stop: https://us.battle.net/support/en/article/56554
We’re going to try getting all of these on to one thread to make it easier to track the issue. Please keep an eye on this thread for updates on the state of fixing the bug.
