Assuming this was an upgrade or reinstall?

Close qBT, then try backing up your BT_backup folder (rename it to BT_backup.old or something) in ~/Library/Application Support/qBittorrent/, then launch qBittorrent?

In terminal you could use:

mv ~/Library/Application\ Support/qBittorrent/BT_backup ~/Library/Application\ Support/qBittorrent/BT_backup.old
