Hi! I assume you cannot use the application after this error. I’m working on it, but for now you could open the settings file at %userprofile%\.msfs_livery_tools.cfg and change the scan depth settings to -1. The config file should looks like this:
[PACKAGES]
msfs_package_path = C:/Users/mikah/AppData/Local/Packages/Microsoft.FilghtSimulator_8wekyb3d8bbwe/LocalCache/Packages
scan_all_folders = True
scan_depth = -1
This would avoid the problematic line. If you don’t want the app to scan any package, just set it to zero. The default setting is 3. Unfortunately, I’ve not been able to reproduce the error in a short try, but I’ll keep the efforts on solving it.
PS: I’ve opened an issue at Github about this bug. Feel free to contribute there too.
