When ever I try to load a new world(or get on to any world) the screen stays on an updating texture pack whatcha ma call it screen and it drives me crazy. Once that screen loads completely and the update is over I tap on the world I want to go on and it won’t select(any button really)

this drives me crazy because it won’t let me play on my worlds I’ve tried creating new ones and it didn’t work 

also is stays on the Minecraft white backdrop for everu

the picture where the world name is highlighted is where I clicked it like 3 times after the updating screen doesn’t work
