Won't launch

Minecraft PE won't open. When we click on it it goes to a black screen for a few seconds and then back to the home screen.
We have uninstalled and reinstalled several times.
I cleared cache and data.
I did a force stop a dozen times.
I deleted a bunch of apps to free up storage.
I made sure all apps were closed.
I searched the issues but have not found a fix.

Minecraft still will not start. Please fix asap. It was working fine a few days ago. We did not update the app or the tablet. There are no updates even available.
