I had the same problem.
This fixed it for me "Render Device Lost" Fix for RTX - #236 by Drakuloth - Technical Support - Overwatch Forums
Anyone having this issue with the new NVIDA driver 445.75 released yesterday I fixed this simply by redownloading the driver and then ticking the “Clean Install” when installing.
Had to apply all my Nvidia settings again but it works.
Hope this helps some of you.
