Help! Following latest update, it broke my jelly fin server!

[C W]

Hi,

I am normally quite resilient and can figure these things out, however i am stumped and broke my jellyfin server.

OS: windows 11 24h2

Running jellyfin on a computer and succesfully using it for a year.  decided to update to the latest and the service no longer starts. 
I have tried changing to local service account or other admin accounts. but starting the service, and it auto stops a seconds after

I have taken a copy of the jellyfin folder, is this enough to restore from?

Yeah, I had that too when the migration effort failed on my machine. I had to get a backup from the earlier in the year before the initial migration started and copied over the config and data directories as well as moving back to a 10.10.7 version to get it to come back up.

From there I've been playing around with the backup and moving back and forth between the two version to see if I can salvage the obviously not going to update libray.db file. I think I may have a non-optimal solution of deleting all of the library.db and .bak/.old files and just rebuilding from there since I can at least get over to 10.11.1 with all of the users intact.

From the release notes:

4. The upgrade will make a backup of your existing library.db file named library.db.old. This file can be used to recover should the upgrade fail. Once you have successfully upgraded and Jellyfin 10.11.0 is running smoothly, you may delete this backup. If you need to try the migrations again due to a failure, stop Jellyfin, rename this file back to library.db, then start Jellyfin again, and the migration will be re-attempted.
