Glad you got it sorted. I just had the same issue with CTDs starting out of the blue yesterday. First they where happening just after loading into a flight and later the sim was hanging on the loading screen. Performed all of the usual steps including emptying the community folder and starting in safe mode; running a repair and then a full reset. Finally, I did the full uninstall and reinstall, but that still did not work. In the end it took 5 or 6 full uninstalls followed by reinstalls  (I lost count there were so many) to finally get the sim to load again. I have got may addons back into the community folder and so far so good after a few short flights.

I still don't know what caused the issue or why it took so many attempts to fix it.

Hopefully I don't jinx anything by posting this lol.

Had same problem. Turned out to be a bad livery for the Ifly 737 max.  Removed it and started normally again.  It’s the Singapore star alliance livery from the Ifly manager.

How the hell does a bad livery cause the sim to be non functional?

 

Imagine downloading a skin for a first person shooter and it causes the game to crash lol.
