Jellyfin no longer starts

[SubsBware]

Server: TrueNas Scale v25.04.1
Jellyfin : v1.2.5

Jellyfin now fails to run. It says "Starting" then stops, then tries again several times before giving up. I manage to quickly get a log snippet (as i dont know how to pull it when its stopped, and the button only appears briefly when it tries to start) and pulled this from it..

Code:

2025-08-17 19:41:37.665559+00:00Unhandled exception. System.UnauthorizedAccessException: Access to the path '/config/config/logging.default.json' is denied.
2025-08-17 19:41:37.665603+00:00---> System.IO.IOException: Permission denied
2025-08-17 19:41:37.665615+00:00--- End of inner exception stack trace ---

I thought this was related to the datasets i made for it, so I've attempted to adjust the permissions, but nothing seems to work. An xi data directory got removed which is what im guessing is now causing this problem, but i cannot figure out how to get it to restore that. Even deleting the app and reinstalling it doesn't fix this issue. 

I'm about ready to pull my hair out trying to get this to work again. 


[Edit] Sadly, i had to wipe ALL of my datasets for it and star fresh  . But its running again.
