Failed to start jellyfin.service - Jellyfin Media Server.

[user1user1user123]

10.10.7+ubu2404 installed with bash script
Ubuntu 24.04.3 LTS

Going to try my first help post before resorting to my default fix-it with jellyfin and doing a fresh unbuntu install. I run a cobbled together setup that (to a novice linux user) seems to have some permissions issues in general.

I accidentally filled up my main drive overnight and neglected to rectify it before turning off my system. Upon restart, I was getting errors with Ubuntu (I think it needed space to update and there wasn't any). I cleared some space and that solved the Ubuntu issue, but upon trying to navigate to Jellyfin I realized it wasn't active. I tried to restart jellyfin but got an error. Stupidly, I don't remember what the error was exactly, and it may have been the same Failed to Start Jellyfin.Service error I'm getting now. I pretty quickly tried to uninstall (using apt purge jellyfin). Uninstall appeared successful, so I tried a reinstall. 

Upon reinstall I still wasn't able to access via browser. I used systemctl start jellyfin and got the following error:

Code:

Job for jellyfin.service failed because of unavailable resources or another system error.
See "systemctl status jellyfin.service" and "journalctl -xeu jellyfin.service" for details.

Tried systemctl status jellyfin.service and got the following:

I next tried replacing config files (/var/ and /etc/ paths) with my backup from a couple weeks ago with the same result. Tried a couple more uninstalls/reinstalls and various troubleshooting I saw in the forums but still stuck here. Please let me know what additional detail I can provide- happy to get logs but not exactly sure how to so might need some instruction there.
