Replacing or Purchasing a Realm - Error Occurred

Whenever I try to select a world to Play on Realm and replace a world on my previous realms it starts to initialize then gives a generic Error Occurred. 

However, I also have issues joining my sons world and people cannot join my worlds. It looks like I'm getting signed out of my Microsoft account a lot as well. So I don't know if this is a bug or I have multiple issues or one issue causing the rest, but this only started after the update two days ago.
