World wont load

I'm using mcpe on a galaxy s8 plus. I was using a nether portal, going from the nether to a monument. Upon exiting the portal a enderman followed me thru the portal and got stuck. After that my world no longer opens without crashing. It crashes during the load up screen and if I get passed that it crashes seconds of being in the my world. I can open up other worlds but this one. I even tried opening a copy of said world but that crashes too. The world is labeled main creative. I just want to get back to my world rather starting over. K thanks
