1.16 Microsoft account black screen bug.

The day the 1.16 update came out I hoped on in minecraft and when it would finish loading and when it should bring me to the home screen, it just takes me to a black screen saying something about signing up to a microsoft account even tho I am and if it just needs me to sign up again I cant because there are no buttons just text so I dont know how to do it. Please mojang help me out here!
