App Crash after random crafting

Playing Minecraft since yesterday on IPhone SE (couldn’t find it in the list).
Game crashes without a message when I try to craft. In my mind it is happening randomly and with random things which I would like to craft.
App crashes and the current „score“ gets lost to a random score before crashing.

In this condition, the game doesn’t make any fun
I tried to reinstall the game, restart iPhone and a lot of other things...
