One more question: does the path C:\Users\mikah\AppData\Local\Packages\Microsoft.FilghtSimulator_8wekyb3d8bbwe\LocalCache\Packages\Community\Learjet35AS_FAF exist? Is there any peculiarity in the file system? As I’ve said above, there is little I can do right now, since I’m not able to reproduce the error and it is supposed not to happen with that specific Python method.
