Unable to play on survival worlds

Whenever I try to go into my survival world it doesn't load and its been happening a lot and when it loads its a black screen that says "leave bed" or "open chat" but then the app closes down. At some point I deleted the app and downloaded it again but the problem still occurs and because I deleted the app I lost all of my creative and survival worlds. The only worlds I am able to play is creative and it sucks not being able to play the world I want so can you please fix this issue.
