When I enter my world it kicks me out of Minecraft

When I enter my world it kicks me out of Minecraft . First when i walk to a specific place in my world it freezes and then turns blue or black, then in about 5 seconds it then kicks me out of minecraft. This doesn't happen in any of my other worlds. I have tried restarting my device deleting things on my phone and it's been like this since the newest update. Please try to do something !! I haven't been able to play with any of my friends because each time this happens!😭
