Copying World Crashes Game

I was trying to copy my world on the Xbox One version of Minecraft, but it got stuck at 40%, and it crashes the game. As soon as I got back on the game, I see that my world has been copied, however, when I play the copy of the world, the game crashes yet again. I think because I have about two or three big add-ons. Is there some way to fix this unexpected bug? Thanks, and I hope there is a fix or a solution to this.
