When I entered the volcano the application closed & Whenever I try to get into my world (named volcano 64) the app closes & I can't get back into my world

As I said in the title, I tried to enter the volcano as I have a second base there, app closed & it happens everytime I try to log back into my world the game closes & gets back to the home screen

I would also like to mention that I am playing on andriod not ios but there wasn't an option for that when the menu opened to choose.
