By reading how it happens my vote goes to corrupt world, but most of the times when I see logs about "corrupt" worlds the log looks different as such I can't really offer an solution.
I think that one of the regions files got corrupted but I would wait before doing anything until someone else has posted

well right before i join and it crashes it says that it was relocating 3 chunks so i tried a minecraft region fixer by Alejandro Aguilera and it said there was no corrupted chunks but 3 errors in chunks but didn't fix them? and a little more info on before the crash i was playing on minecraft while computer got unplugged so that might be the cause
