Can't get Plex to stop asking to select user at startup

Someone else had the same issue:

Regain Plex Admin after accepting invite from other Plex user

My roomate has a Plex server and sent me an invite to access his server. I accepted it and it now list his Home user account with the crown in my Plex. He doesn’t have access to anything on my server. I don’t know how to remove him as a listed user with the crown on my account that is assigned to my email, not his.
