Pocket Edition 1.13 crashes before loading screen.

After updating the game it will no longer go past the Mojang screen. It crashes straight away. I've tried reinstalling. (Not happy I lost worlds from when the app first launched.) I've also tried doing a soft reset many times (Before and after reinstall.) and there is no difference. I'd prefer not to do a factory reset of my tablet. I'll only do so if its my last resort but I fear it wont do me any good.
