Launcher just closes after clicking play

Hi... Don't know what is happening, never had this problem before... Used to play MC everyday and it never bugged like this... Now, everytime when i try to play minecraft i run the launcher, click play and nothing happens, the launcher just close...
If i try to make a new configuration, after download a ton of things it shows me
