Last time I played minecraft, I was playing multiplayer and was waiting in bed in a night cycle for another player to get into a bed. They didn't end up in a bed and I wanted to close the game, so I pressed the close window button in the top right. I still remained in the bed. 

I tried to launch that world again today and it loaded me in the bed, with the "leave bed" and "open chat" option buttons. If I wait, the game crashes. If I press the buttons to leave the bed or open chat, the game crashes. 

This is a fairly large world, over 350mb because I've worked on it for over a year and a half now. I had exported the world from my old laptop to my gaming PC. Another thing to note is the profile photo for the world does not match up to where I had slept last.
