Show sleep screen when I load into my world then crashes

I have the same issue. I've spent many hours in one of my survival worlds and out in a lot of hard work into building and other things. Then today when I tried to join the sleeping screen showed up instead and then the game crashed. I tried to make a copy of the world but the same thing happened.

Thank you for your report!
