Unexpected fatal error when launching SC2

Hello, I have a issue with launching SC2 to start play. After I pressed the play button, the game start load, after that the screen turn to black for a 2 sec and after I see the HOTS cursor the game shut down with an “An unexpected fatal error occured” window with this code:
