Recent Plex Update has broken plex media server, many threads about this

Hello Plex team, I think your latest update completely broke plex media server. I can’t connect to my local server, even on the host computer. When you open the plex server, it just defaults to a web app login in screen. if I sign in, it says to install plex media server even though I already have it installed. Can you please comment as to if this is an issue with the newest version, and if so, when this will be fixed? I cannot use plex at all right now.

If you look here and on reddit, there are multiple people having this issue.

The version is the newest from yesterday.
