Can't open my survival world.... When I try to open my world, it loads and suddenly crashes, gets me back to my home screen.

When I try to open my survival world, it takes a kinda long time loading the resource packs which is different from the other worlds I have.. when I load my other worlds, it loads resource packs very fast and generates the world.... But on my survival world, when it starts on generating world, my screen suddenly turns black and crashes the whole game.. hope you can fix it... Thanks..
