Irregular crashing to desktop

I am getting irregular crashes all right to the desktop. They all generate a Fenris error (example, but they are all different: 88933F99-E018-4B94-87A3-932E6E9026A8). Also, they are not regular as sometimes I can get through a complete 45min Helltide without crash. Very frustrating when in a party, especially pit runs! Never had a crash in the previous 2 seasons. I have tried numerous things including turning graphics way down (hardware support off and disabled, running in a window, updating sound driver) . I haven’t tried uninstall/reinstall yet but that’s next.

I played season 9,but last season I played was 4.D4 is bad this season for crashes,I don’t think the game crashed twice in 4 seasons. Now it’s just a mess of poorly optimized code lol.
