Brief description of the issue:

Since purchased FS2020, I never had this issue but today this CTD started.
FS2020 is starting normall. I could go to plane, fly now and I am being at airport but randomly it is crashing out of nowwhere. Also what I have observed is if I start Vpilot, it is freezing ann causing CTD, if i am starting FShud, it starts crashing. It frezes and then after 5 secs, it will crash.

I have US language pack installed, I verified C++ distributables by reapiring them but of no use.
Please help anybody.

That’s likely related to this post on the dev support forums, if you encountered the problem with the PMDG 737:

https://devsupport.flightsimulator.com/questions/13314/ctd-two-flight-simulator-crash-dumps-when-using-pm.html

We have a bug on our side that can cause crash if the title is longer than the allocated SimConnect string.
In this case, Tacview seems to request titles on 64 sized strings and the PMDG aircraft title set in aircraft.cfg is longer than this.

We are aware of the bug and this will be fixed in SU12 but an easy workaround in the meantime is to edit the PMDG aircraft title so that it takes strictly less than 64 characters.
