LR won't restart

[robtarrphoto]

I was doing some syncing on a few folders and after I shut down (and saved a backup) LR won't restart. It keeps creating -shm and -lock and -wal files on startup (even if I delete them) and won't restart.  Any fix?

The creation of those files at startup is normal. Try resetting the preferences: https://www.lightroomqueen.com/how-do-i-reset-lightrooms-preferences/

Ah problem solved.  I just copied the last backup file over and she restarted perfectly...
