I didnt want to post this too early as it may not even be a thing.
I like many others have had this problem since Friday/Saturday of which I never had no issues previously.
I am running SU10 beta and my WIN11 installation is fairly new, so was not expecting any issues. The PC I run MSFS is a dedicated FS computer, so if something goes on it, I pretty much know about it.
I like some searched for the ntdll error and it was suggested like mentioned above about doing a sfc \scannow commmand in your command prompt. To my surprise it found some windows protection errors on it and has subsequently repaired itself. I am fairly up on PC maintenance but this is an area I don’t usually fequent.
The CTDs were abysmal last night to be truthfully honest, but this morning I have just flew from SFO to LAS with the PMDG and things went really smooth. Now I don’t want to jump the gun here and say what happened has fixed it but I see what I see.
I am going to be flying all day today and happy to report back if anything happens.
