It won't let me log into my Minecraft account, and it throws me the screen as if it were a console

This morning I tried to log into Minecraft but my account wouldn't load, And it didn't let me log in because it threw me out as if it were a console, and when I tried to do what it told me on the Microsoft page it gave me an errorI would like a solution please, as it seems very unpleasant to me not to be able to enjoy the Realm I rent and my purchases from the marketplace.
