I noticed something else: I can no longer connect to multiplayer worlds or servers. When I go to the skins section, all the buttons on the left side of the interface don't work; they just click and don't change the screen. I'm having trouble logging out of my Microsoft account. Here are some extra screenshots I was able to take.
The main problem is that it doesn't allow you to change the skin, and also, when you open the marketplace, it just gets stuck on the loading screen and nothing happens.
I can't see my friends list either.
