Problems after migrating to new server

[windbreaker_familiar]

Long time Jellyfin user here, first time posting on the new forum.

I recently migrated my JF setup to a new server (both Linux). I restored the data and config directories, and most things came back just fine. The only issue I've come across so far, is that I'm unable to make any changes to any libraries. Trying to select "Edit Images" or change any settings under "Manage Library" Gives me an endlessly spinning circle. 

Any thoughts as to why?
