Survival World on IOS device will not load

My survival world will not load. Whenever I try to play, the green loading bar will fill all the way up and just stay there. More random text will generate in the loading screen, but the bar will stay there. Every other world I have on my IOS device will generate and I can move around fine. I have tried making copies and restarting my phone to no avail. I want access to my survival world again.
