Unresponsive after 10.11. upgrade - morytox - 2025-10-27

Hi Community, 
 
i recently upgraded my Jellyfincontainer to 10.11. and have issues accessing most of my mediafiles ever since. 
My music does not load in apps. If i want to access it in webapp, every library loads for many seconds. I either get an empty list, or if it loads all my albums and i play it there is no source for it available. But if i open the album to see details and wait again many seconds until all songs are listed, and play a song it does play it. 
It seems that any action i do has a VERY long response time associated.

RE: Unresponsive after 10.11. upgrade - morytox - 2025-10-27

Also full library scan runs quite easily to ~95% and slows down very much to a hold but finishes after quite a while, responsiveness does not change though.
Also what's weired: I read in changelogs to disable plugins. Now when i try to deactive them, they prompt me with restart, but stay activated after app restart.

As for my plugins:
   

i cannot deactivate them, as i toggle them to inactive it prompts me with restart and after restart they are active again.
