CTD during loading game even after clean install


I can now confirm it was a Steam save data corruption. My installation is fully working now after doing these several steps:

  1. Disable MSFS2020 Steam Cloud Backup

  2. Delete save data folder (C:\Program Files (x86)\Steam\userdata\ {steam user id}\1250410)

  3. Clear Steam Download Cache

  4. Relogin to Steam

  5. Recheck MSFS2020 Steam Cloud Backup is disabled

  6. Start the game

I have to thank these two threads (which I think are caused by the same issue of this thread):

EDIT: Fixed the links

@PeterP999 and @AirshipCrown9, I hope this solves your issues too.
