[solved] PhpStorm 2016.1 crashing at startup on OS X Mavericks

Hi,

I just updated from PHPStorm 8 to the latest PHPStorm 2016.1.

But after giving authorization to OS X to launch the program (1st launch), the software launches and then immediately exit. I can't barely see the icon appear in the dock...

Where can I find information about any error, or other help ?

Many Thanks
