Can't load, crashes after trying to open a world. When I select the world I want, after a couple of seconds I am taken back to the Minecraft Launcher and get an error report. This is my 11 year old son's game, so I am not familiar with an updates that need to occur, or how to do anything but load the game
We tried all 3 of his offline worlds and none will load.

Steps to Reproduce:
1. Open Minecraft (opens Minecraft Launcher)
2. Select Play Offline
3. Select the world you wish to play
4. Crashes and returns to Minecraft Launches with the attached error report
