HELP ME PLEASE, it's been going on for a month

it isn’t allowing me to enter movie worlds unless it is Gens World. LS media doesn’t work nor does MOVIE AND CHILL. i do not know what the issue is because it was working once before. When i try to enter it kicks me off back into the loading screen and shows me a world which is pink and black. then it kicks me out again and takes me to the “ERROR WORLD” Please how do i fix this. i just wanna watch a movie.
