Nvidia GPU? If yes …
FYI, with Nvidia driver 572.16/572.42/47/60,70,83 Nvidia app and DX12 selected in MSFS 2020 a CTD won’t occur.
However, with DX11 selected in MSFS 2020, using the same latest Nvidia driver and Nvidia app, a CTD will occur.
Until Nvidia fixes the application and Asobo MSFS 2020/2024, please check what happens if you select DX12 instead of DX11 by manually editing cfg file.
To do this, you need to edit usercfg.opt file and modify the line
PreferD3D12 0
Change the number 0 to 1
and save the changes.
OR
If you need Nvidia app, make sure to select DX12 instead of DX11 in Nvidia app and the profile for MSFS 2020.
// optimize MSFS 2020
OR
If Nvidia app installed go to:
c:\ProgramData\NVIDIA
delete folder named NGX
