I'm afraid your database got corrupted somehow. If you put your database on a network drive or on Dropbox, that could happen if two programs try to access the database at the same time. You could also have a failing harddrive.
Do you have other backups outside of Dropbox? You could also try the backups Mnemosyne creates itself: https://mnemosyne-proj.org/help/backups.php Good luck!
