Game Crash on specific world at start up

My minecraft world is crashing when it is loading, at 92%. The error message says "An unexpected issue has occurred and the game has crashed. Sorry for the inconvenience " This only happens when I try to load one of my worlds, called Project. The other worlds load fine, and I can create new worlds. i tried optimizing the world, backing it up, and saving it multiple times, I tried to open it in an older version, and nothing worked.
