[Bug Report: MSFS 2024 Crashes Related to WTF.dll & FMA Issues]

For those who faced WTF.dll error, can try not to click the navigraph chart or enroute section in the OIS (can still use navigraph data in 3rd party section) in the whole flight. I have tried multiple flights (using v1.0.8, flight time around 2-3 hours) by doing this seems didn't CTD again. Not sure if it is related.

I never use enroute section but I do use navigraph charts and I had issues when using liveries and didn't when using the all-white livery, this does not necessarily mean anything but I observed consistent crashes and it just working based on if I am flying a livery or all-white. I am still thinking it's the liveries that are involved somehow and maybe even multiple systems contributing to these crashes.

Update:
I just finished a flight with the A350 from gate to gate without issues when flying the all-white livery again so I am 99% sure that the WTF.dll crashes are related to the liveries. I haven't tried flying the inibuilds house livery but it either crashes because it is a livery being applied to the default white one or it doesn't crash because it was included with the plane installation and is not a separate instance. 

If immersion is everything to you don't fly the A350 for the time being, if you don't care: fly the all-white livery and default sim nav data to be on the safe side.

I can pretty much confirm that reinstalling the liveries and then flying with one just causes the WTF.dll module to crash again flying the same route I flew yesterday with the all-white livery without issues.

The last couple days I have not been able to view the display screens to change the navdata. When I try to load on the runway, all the screens are blank and I get an audio STALL STALL message even though the aircraft is on the ground.

When I try to load at a gate the EXT 1 and EXT 2 show AVAIL but when I click on BAT 1, all I hear is a faint click and nothing powers up. I've tried using the all-white livery but that hasn't made a difference.

The all-white livery is what I found resolved the wtf.dll module crashing for me. The only thing I would suggest is a full reinstall if you haven’t tried that already because what you are describing is not what I have seen or heard of until now so nothing as far as I am aware is known about the issue you are having.

I believe I've identified what’s causing the WTF.dll module to crash, and here’s how I came to that conclusion:

Yesterday, I began running test flights:
I completed a ~3-hour flight in the -900 variant using the default sim NAV data and the all-white livery. The flight went smoothly from gate to gate with no issues.
I followed up with a much longer ~8-hour flight in the -1000 variant, which ended up lasting nearly 10–11 hours total. This time, I used NAVIGRAPH navigation data, but again stuck with the all-white livery. No issues or crashes occurred.

Today, I decided to fly the FINNAIR livery from Helsinki to Tokyo and during this flight, the WTF.dll module crashed again. While I can’t be 100% certain yet, the pattern suggests that the crashes may be related to liveries, not the navigation data or aircraft variant. I haven’t yet reinstalled the liveries (since I doubt it’ll change anything), but I’ll try that next and share an update tomorrow.

In the meantime, I recommend that anyone experiencing similar issues try flying with the all-white livery, even if it breaks immersion. At least that way, your aircraft should remain functional.
