Game freezes on loading screen

when the main loading screen with the Minecraft logo appears, it loads a little and freezes. I keep reopening, but it is frozen.

the app seems to be running, but the loading screen is not loading properly on iOS.

it is not a problem just with my iPad, I tried it on my 2 spares but it still didn't work.

if anyone else has had this problem, or knows how to fix it, please comment down below.
