UE - Packaged game window starts full screen but non selected, why?

Hi, after packaging my project and launching it, the game starts, but the full screen window of the game is not selected by default, I have to click it with the mouse, If I don’t the game starts without sound, because the the game is not selected at launch.

This is mostly an issue for console testings, If I need to make a first click with the mouse to the game window after launch, but instead I decide to start using my Xbox, not the mouse, the Xbox version won’t respond unless I use the mouse to click over the game window, then I can use the gamepad.

What can I do? please help
