jellyfin won't launch since 10.9.11 update

Did your disk fill up at any point recently? At this point we should start over since it seems clear that your database is not in a good state. I'm not sure what else we can try.

If you are ok with that, follow these steps to backup your current data.

Code:

sudo mkdir /var/lib/jellyfin/backup /etc/jellyfin/backup
sudo mv /var/lib/jellyfin/* /var/lib/jellyfin/backup/
sudo mv /etc/jellyfin/* /etc/jellyfin/backup/
sudo rm -rf /var/cache/jellyfin/*
sudo systemctl start jellyfin
