I hadn't flow in TNCB for a while. I tried starting a flight from TNCB today and this is causing a CTD.

MSFS version:

TNCB version:


I tried loading the flight with FBW A32NX and then with a default aircraft, but I had a CTD in both cases.

I am using Navigraph (latest AIRAC version installed), FSUIPC, and FaceTrackNoIR.


Are you aware of any potential conflicts with other add-ons?

Please let me know what other information I can provide for the investigation.

(edit: I forgot to add MSFS version)

Below are the Event Viewer logs at the time of CTD.

I read that the ntdll.dll issue could be due to Windows not being up to date, but I just performed all updates (windows and drivers).

Please let me know if there is something else I can provide.

This happens when loading a flight, so before I even see the airport.

After removing all my add-ons from my Community folder, it is working fine.

However, I have 600+ add-ons in my community folder, so it will be impossible to find the one that may be causing a conflict.

Have you had any reports of conflicts with specific add-ons such as Navigraph, mobiflight, etc.?

Anything that could help finding the culprit would be really useful.

TBH, when you think you need 600+ addons, it can be guaranteed that there will be problems. Even in my best times with FSX and P3D, where I had really a lot of addons, I never came close to such a number.

Only advise I can give you: think about what you really need and do not install everything that is available. ;)

Thanks! If I manage to find the conflict, I will post it here in case it helps someone else.

Many of these 600+ add-ons are liveries, and payware or good quality freeware sceneries 🙂

I may have to try one of those tools yes!
