Minecraft shuts down just after opening a world, no matter if it is a new world or an existing one.

What I expected to happen was to start the game!

What actually happened was:
After showing me the usual "Loading world...Building terrain,,," the game seems to start, but after some seconds the window shuts down and i get an error-message.
Bevor the newest update, i got a bug-report, but now i just get a "sorry mistake..."- message.
Screenshots and bug-report attached!

Thanks for helping! My son waits so hard to be able to play finally!!!
