Minecraft Pocket edition 1.5.1 using an Apple Ipad model MD512LL/A with IOS 10.3.3 is not opening after creating a world. 

Steps to reproduce the problem:

1. Download from app store
2. Start the app
3. Create a new World and hit play
4. The app crashes and won't open again

The same behavior after trying to sign in. The app won't open again.

I tried reinstalling the app and had the same behavior.
