Full screen black when the game is packaged

Hello,

I seem to have a problem when I package the game and run the game in fullscreen mode, the screen becomes black. I created a an .ini file DefaultGameUserSettings.ini and used the following settings:

[/Script/Engine.GameUserSettings]
bUseVSync=False
ResolutionSizeX=1920
ResolutionSizeY=1080
LastUserConfirmedResolutionSizeX=1920
LastUserConfirmedResolutionSizeY=1080
WindowPosX=-1
WindowPosY=-1
bUseDesktopResolutionForFullscreen=True
FullscreenMode=0
LastConfirmedFullscreenMode=0
Version=5

If I just launch the game (it lunches in windowed mode) it works correctly.
What could be the issue?
