Game Crash right after launching

After starting the game with the (fresh installed) launcher the launcher closed and then opened again. A view to the Development Console told me that the game crashed.

What I expected to happen was...:
I expected the titlescreen of Minecraft to appear.

What actually happened was...:
Nothing...
Well maybe the Output of the Development Console can help you:
