Paswort reset - no longer any media availabe

I reset my password and now my library is gone.
Plex server is on the same windows machine.

now what? I removed some credentials from the registry and restared window.

Nothing.

okay I did all that now I just get this screen in the plex app:

plex server is installed and runing. In that oterh article on how to reclaim a server it says on click of the plex server icon some prompt should show up. but there is nothing happening.

nope. nothing of that sort has ever happened.

hello. anyone there?

I uninstalled everything and reinstalled plex server and the plex app. nothing changes. the plex ab doesn’t recognize that plex server is installed and running localy
