mcpe crashes when loading worlds

I can play in other peoples worlds and servers. However, when I try to load a world it either crashes right away, some point during the loading, or occassionally right after it loads. 

I went a long time with no issues but around the update before the first aquatic update, I started having the crashes. Been hoping an update would fix the problem but no luck so far. 

I have plenty of room on my kindle and it works just fine with other games and apps.
