Crashing

I open the launcher to play Minecraft but when I click on the "Play" button the launcher will disappear for a moment before reappearing with an error that reads;

                                                               ERROR

                                                         Game Crashed

An unexpected issue occurred and the game has crashed. We're sorry for the inconvenience.

 

I click "View crash report" but it opens nothing. All I can do is close this pop-up box and the launcher. I've tried countless times uninstalling and installing Minecraft to try and fix it but it doesn't work. If anyone can help, please ASAP.
