To try to isolate what is causing the CTD
Look in the Windows Event Viewer and get the
Faulting Module Name

I had the same problem yesterday evening. I' m afraid that it has to do with the new Windows 21H1 which came out lately. Before the update I didn't have any problems.

Before the Windows update I didn't change anything on the Prepar3d installation.

I didn't update the Nvidia driver as well. Unfortunately I didn't make screenshots from the application log file but I remembered it had to do with certain rights on a registry key (Dword).

I did a complete vanilla W10 reinstall but I didn't install Prepar3d 5.1 yet. Tonight I will do a vanilla P3d installation and will report back.

Sorry for not being a big help yet.
