CTD when launching MSFS 2024 (suddenly)

Hi there,

I can find a lot of those issues for MSFS 2020, but I've got one for MSFS 2024:

After it has worked with hardly any flaws for half a year, MSFS 2024 suddenly started to get CTDs when I was at bigger airports. After some of them, a DXGI ERROR_DEVICE_HUNG (0x887a0006) error message came up. Some people said the NVIDIA app caused this problem. So I uninstalled it. Furthermore, I did what was shown in the video below. At first, it seemed solved. Then the inibuilds A330 ran completely crazy. So, I tried to download it (instead of streaming). After that, it worked normally for a single time. And then the whole sim ALWAYS crashes as soon as the splash screen appears for a few seconds. No chance to even get to any menu or settings page within the sim.

I deleted the whole Community folder. Again, the first time it worked. And since the second time, again the same CTDs. Driver of the graphic card (RTX 4070 ti super) is current. I did exactly nothing exept loading the latest mandatory update of the sim. But the described problems started before that. Very frustrating. I can's touch the rolling cache, nor any graphic settings in the sim. And I have no idea, where the problems are coming from. First I thought, it had to do with Beyond ATC, the FSLTL AI traffic models, TrackIR or APL. But it also happens with ALL of them deactivated.

The only suspicious thing so far was, that the WASM folders are not where they should be and are very incomplete.

I feared it would be a hardware issue. But MSFS 2020 runs smooth and stable with quite some complex addons installed. And anyways, everything else on my system is running stable, too. Have you got any idea, where to start troubleshooting?

My system: Intel Core i7 9700K @4.4 GHz, ASUS Prime Z390-P, 32 GB DDR4 RAM, Nvidia RTX 4070 ti Super, BeQuiet 850W PSU.

Thanks in advance.

Best regards,

Dominik
