Whenever I open Minecraft and click on singleplayer, it will load singleplayer but not multiplayer. Multiplayer will load the loading screen then immediantly exit out to a crash report launcher.This has happened about 8 times in a row now.

Steps to Reproduce:
1. Click on Play on the launcher
2. Wait for MC to open
3. Click on Multiplayer
4. Loading screen is at dirt screen for about 2 - 3 seconds
5. Will exit out to a crash report launcher
