Hello, I was having this problem and reached out to Just Flight support. I thought it might be helpful to share their reply here, as (as far as I can tell) I seem to have solved the problem by following some of their suggestions.
In my support ticket I had let them know that my Community folder was completely empty, and that I was getting CTD with Windows showing CoherentGTJS.dll or CoherentGTCore.dll as the cause of the crash. Of their suggestions below, I only did two things. I cleared the shader cache (Google how to do it, there are a few more steps than they describe) and I uninstalled and reinstalled all of the Visual C++ redistributable libraries (available from Microsoft, google it). I have not been getting CTDs any more (so far, and granted it was hit and miss when it was happening).
Here's their full reply:
Crashes involving CoherentGTJS.dll or CoherentGTCore.dll are commonly reported in applications like Microsoft Flight Simulator (MSFS) and are typically related to UI rendering issues, as these DLLs are part of the Coherent GT UI middleware used for in-game interfaces.
The common causes for this issues are:
Memory corruption or heap allocation issues – These DLLs often crash due to corrupted memory pointers, especially when interacting with other mods or third-party content.
Outdated or incompatible GPU drivers – Many users report that updating or rolling back GPU drivers can resolve the issue.
Corrupted installation or cache – A fresh install of the game or clearing the shader cache sometimes helps.
Outdated Visual C++ Redistributables or DirectX – Ensuring all runtime libraries are up to date is essential.
Here are some steps you can try:
Update GPU Drivers:
Use the latest stable version from NVIDIA/AMD.
If the issue started after an update, try rolling back to a previous version.
Update Windows and Runtime Libraries:
Ensure Windows is fully updated.
Reinstall the latest Visual C++ Redistributables and DirectX.
Clear Shader Cache:
For NVIDIA: Go to NVIDIA Control Panel → Manage 3D Settings → Shader Cache → Clear.
