I’ve experienced the same freezes (2 out of 4 flights) lately, but in the meantime I completely changed my gaming PC and reinstalled everything 5 days ago, Windows too, so it was hard to pinpoint the culprit. Reading this post has been helpful, so I’ll check the nVidia drivers and do some tests (3080 Ti here). For me MSFS freezes but everything else on the background still works, sound too. No real CTD or error messages. I can quit MSFS via Task Manager. So frustrating. Can you download older driver versions from nVidia website? I’m going to check now… Thanks everyone!
EDIT: after reverting back to the previous nVidia drivers I completed succesfully two flights without problems
