Going around in circles adding Plex Media Server

Server Version#:?
Player Version#:.1.112.0.359-0d79a49f
<If providing server logs please do NOT turn on verbose logging, only debug logging should be enabled>

Running Windows 11 on laptop. Was very stable but now constantly getting laptop unavailable, not authorised etc. Deleted server and select get Plex Media Server etc. When I select that, it just offers me chance to open it. I select that but nothing changes on main Plex for Windows app.

I’m running Norton 360, so that may have something to do with it?

Any wisdom greatly appreciated. Just don’t want to have to constantly sign in and out of apps.

Thank you
