Maybe your song folder path is invalid? Try launching with USDB_Syncer-0.20.0-Windows-install.exe --songpath .\songs or similar. If that works, you can change the path to something valid permanently in the GUI. And please let us know if that was indeed the issue, then we can catch that error in the future.
