1. I press the MCPE app and I wait for about 20 secionds then it crashes

I open the MCPE app and it crashes after 20 secionds (in 1.16.1)

how I caused this: I was installing addons for mcpe and then i found a medieval mobs addon on mcpe.dl.com i installed it and then loadad up a new world but it was loading slow becuase i already had a pe gui addon and a custom and addon resoures ack install so i quit mcpe and then it would not load.
