Hello,

As its the weekend you may not get the proper support on here, all I can suggest is a reinstall and clear the scenery index. 

 

I tried this but it did not work.

[CTD at EGLL - Exception code: 0xc0000409]

I have a strange issue that’s just started happening this week.  I haven’t changed / updated anything (that I am aware of).

When loading into EGLL enhanced, the sim will zoom in as normal, the “ready to fly” icon appears but then everything freezes for about 20 seconds, then a CTD.

The appcrash log states:

Exception code: 0xc0000409

Exception code description: The system detected an overrun of a stack-based buffer in this application. This overrun could potentially allow a malicious user to gain control of this application.

Fault Module Name: FlightSimulator2024.exe

What I have determined is:

1.      This only happens at EGLL (I have the latest version)  - I also have iniBuild EGKK and it doesn’t happen there.

2.      All non iniBuild airports that I have tested (native and addons) work without this issue.

3.      It only happens with certain aircraft – it happens with flybywire A380, Horizonsim B789 but also some native MSFS2024 aircraft such as the TBM and others.

4.      It does NOT happen with the iniBuild A350, PMDG772, Fenix (only tested the A319 but assume all work). Or at least the few times I have tested these to load into the sim (not flying) I don’t get the CTD.

5.      This issue happens regardless if I load into a gate as cold and dark or directly onto the runway.

I have run out of time to test other scenarios but though I’d post before I get too much further into this, in case someone else has seen it, fixed it or can advise?

Also note that I have tried all the usual stuff that MS advises around file scanning, virus checks etc

[Certain Terminal Buildings Not Loading]

Same for me.  Just returned from LAX, c10 hours of flying and no T3 on arrival.  Its not the first time its happened, seems to happen only when arriving into the field, not if you load into LHR for departure.  I've tried the various fixes mentioned above and none of them work.  If I go back to "main menu" and re-load onto the same stand as I parked at on arrival, the buildings appear as normal.

Very frustrating!!
