LAUNCHER CRASH UNLIKE ANY OTHER.

So it says I need to get straight to the point. Basically, I crash every time I try to click that "play" button on the minecraft launcher. I tried it with the regular updated version (1.8.8) and it crashes. When I used a profile with OptiFine 1.8.7, it gets worse by crashing AND auto quitting the program.

So. Yeah. Here's the crash report. I do hope you can help.
