I’ve had this same issue. The fix was to completely revert my graphics card drivers to a previous build I knew to be working (this was around the time the latest OpenGL spec was announced, which is funny considering this is DirectX I believe, maybe just a coincidence)
Mostly the “it’s just your personal system” is a pretty unhelpful answer to be honest. Everybody’s problems are going to be unique to their experience but for now you’re just going to have to try going intot the NVidia device settings and try changing features till it works.
SLI systems face reliablility issues here, as there are a lot of known bugs with SLI and Overwatch.
