Screen problem (Mouse Event not found) followed by OpenGL crash

What I expected to happen was...:
The game should start...

What actually happened was...:
After restarting the game because it crashed as a Mouse Event was not found (as klicking FULLSCREEN), Minecraft crashes everytime on the startup of the actual game UI.

Steps to Reproduce:
1. Start MC
2. Go Fullscreen (F11 or in the Options) to crash it
3. Get the following error:

Description: Updating screen events

java.lang.IllegalStateException: Mouse must be created before you can read events

4. Close the game entirely
5. Start it up again
(6. Crash before Minecraft Logo screen)

Actual Crash (OpenGL):

Description: Unexpected error
