World crashes for unknown reason. HELP??

I was name tagging all my villagers different names, I think there were 10-17 of them, then I talked to a librarian that was named, looked at a enchanted book it was selling, and then the game crashed. I am unable to get on that specific world now.

If specific details are important, I had previously made a bell and removed the bell that generated with the village. Then I Placed the bells down in places I found more appealing, one at each end(ish) of the village. I was also on peaceful, and the village had two iron golems.
