Issues after reinstalling Jellyfin on CasaOS

[FigmaCode]

Hello!
I recently got my first NAS and installed Jellyfin without any problems. However, when I noticed that not all of my libraries were showing up in the Swiftfin iOS app, I tried to troubleshoot the issue. To investigate, I created a new test library using a randomly chosen path, since it was just a test and I didn’t want to create a new path.
After doing that, my server seemed to go into an infinite loop, and Jellyfin started using 100% of my CPU. Unable to find the root cause, I decided to uninstall the Jellyfin Docker image (I installed Jellyfin through CasaOS using Docker) and then reinstall it.
Now, when I try to enter Jellyfin, it prompts me to either add a new server or connect to my old one, but neither option works. It just says that a connection is not available.
How can I completely remove Jellyfin and all related data to start fresh?
Thanks in advance!

If you still have the logs from the first docker image, we can try to diagnose that. Share those via pastebin, if you still have them.

For the new one, you'd need to clear your browser cache.
