0.11.1 Crashes on opening app

0.11.0 worked perfectly for me, but when I updated to 0.11.1, the game immediately crashed on startup. It shows the Mojang logo for a split second then crashes every time I open it. I have tried restarting my device, but no good. I would prefer not delete and reinstall so I can keep my worlds.

I would have marked the version as 0.11.1, but the list said it doesn't exist... sorry, screenshot, you're wrong.
