Failed to start Jellyfin, migration issue? - skellumtv - 2025-11-12

I recently updated my Jellyfin to 10.11.1 and it was running fine.
Today it isn't accessible and when navigating to the server it tells me Jellyfin failed to start in time and to check the logs.

I've updated to 10.11.2 and still am receiving the error, here is the latest log.

This appears to relate to migrations but I'm not migrating, the server is the same Windows 11 build it has always run on.

Can someone advise here please?

Thank you

After googling and finding nothing, I deleted the migrations.xml file under Program Data\Jellyfin\Server\Config and the service started successfully.
Server now appears to be back up.
