"Content Browser Unavailable"

I was in the middle of using Forge when I noticed I couldn’t save anything, save, save as, save prefabs, etc. I backed out to the home screen and restarted but whenever I try access my files a banner comes to up with “Content Browser Unavailable”.

Is this something on my end or did someone over at 343i accidentally trip over a cable?

Happened to me only once, I just came back another day and it was fine.
