Not able to start (exit code:1)

Hi there.
I played the Game this morning. everything worked well.
On the evening, the game did not start.
I deinstalled the whole Minecraft, including the folders minecraft wasn't able and started a whole new Installation to make sure, it wasn't my fault.
Big Problem: The Game still won't work.

I saw in the half command (red marked in upper log) some argument i cannot change, it is not visible in the profile command-list but the error message "Error: Could not find or load main class net.minecraft.client.main.Main"
is propably the reason, why the game won't start.

Any Suggestions ?

PS: I also tried the alternative launcher as described on another topic, but the error is still there.
