Crashes right when joining a single player world: java.lang.StackOverflowError

My minecraft crashed a few days ago and I tried to get back on to my (single player) world. The loading screen comes up, and right when it would put you in your world it crashes. Every other single player and multiplayer world works just fine except this one. I have tried treating it like a corrupted world, creating a copy, replacing the .DAT files with a blank world's, and it works, it is super laggy, and it crashes for no apparent reason. After a few crashes, the same issue happens, and the launcher log looks the same. I have no idea how to replicate this, since it came out of the blue and completely surprised me.
