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

[pijnackerpilot]

Description: I have encountered persistent crashes in Microsoft Flight Simulator 2024 (MSFS 2024) while flying, with the application consistently failing and crashing due to issues with the WTF.dll module. The crashes occur intermittently during the flight, specifically either during the flight loading process or during the cruise phase of the flight. This issue started about a week ago after I installed version 1.0.8 of the inibuilds A350.

Additionally, I have encountered several bugs after recovering a flight via autosave, including:

1. Inability to activate ALT CRZ mode in the FMA.

2. During Open Descent or Climb, the aircraft busts through the set altitude and does not follow the altitude constraints, unless manual level off is used.

3. ALT CRZ mode remains blue in the FMA and does not engage properly.

Crash Details:

• Faulting application: FlightSimulator2024.exe

• Version: 1.3.23.0

• Faulting module: WTF.dll

• Exception code: 0x80000003 (breakpoint)

• Fault offset: 0x00000000000023cb

• Faulting process ID: 0x1050

• Crash occurs during: Flight loading or cruise phase.

• Log Entries:

  • First crash: Occurred at 16:48 UTC, with the WTF.dll error, while trying to load or during cruise.

  • Second crash: Another instance at approximately the same time, with the same error related to WTF.dll.

Steps Taken So Far:

1. Reinstalled GPU drivers: I updated my graphics drivers (NVIDIA drivers) to the latest version, but the issue persisted.

2. Checked for Mods: No new mods or add-ons were added recently to the community folder, and all add-ons were disabled to test the issue.

3. WTF.dll found at C:\Program Files\WindowsApps\Microsoft.Limitless_1.3.23.0_x64__8wekyb3d8bbwe\WTF.dll.

4. Problem began: The issue began after installing version 1.0.8 of the inibuilds A350 addon.

5. Bugs after autosave recovery:

   • ALT CRZ mode in the FMA cannot be activated.

   • During Open Descent or Climb, the aircraft busts through the set altitude unless using manual level off.

   • ALT CRZ mode remains blue and does not engage properly.

Observations:

• The crashes do not occur during landing or approach, but only during the flight load process or while cruising.

• The issue seems to be related to the WTF.dll file, as indicated by the crash logs.

• The application repeatedly crashes with the same error in WTF.dll, even after troubleshooting steps.

• The FMA bugs (unable to activate ALT CRZ, altitude busts during open descent/climb, and ALT CRZ staying blue) only appear after recovering from an autosave.

System Information:

• OS: Windows 11

• GPU: RTX3080

• MSFS Version: 2024 - 1.3.23.0 

• Driver version: Latest NVIDIA driver 

Request: I am requesting assistance with troubleshooting or a possible fix for this issue. Has anyone else experienced similar issues with the WTF.dll file in MSFS 2024, particularly after installing version 1.0.8 of the inibuilds A350? Additionally, has anyone encountered the bugs related to ALT CRZ mode and autosave recovery? Any advice or solutions would be greatly appreciated.

I also have an issue with wtf.dll CTDs after updating to v1.0.8 with the same exception code. So far I was not able to complete even a single flight without interruptions after V1.0.8. I would just be cruising (with the elapsed time ranging from 3 - 6 hours) without touching anything and all of the sudden the sim just closes. V1.0.7 worked fine for me and it would be great if there can be a solution for it. 
 

Steps taken:

Installed latest driver, cleared WASM folder, emptied community folder

Specs: i7-13700K + 64GB ram + 4070Ti

Driver: Latest NVIDIA driver
