Jellyfin Clients not working

[TheDreadPirate]

You mentioned the registry, but did you delete the two folders I mentioned? They are the app cache for JMP.

To clear the JMP cache go to C:\Users\yourUser\appdata\local.  There will be a "jellyfinmediaplayer" and "Jellyfin Media Player" folder.  Delete both.  Open Jellyfin Media Player and log back in.
