Thanks for your replay JoeViking245
I've managed to fix the issue by writing a "Resume Script" for duckstation,
I'm starting the duckstation as fullscreen, the issue when I resume the game from the pause screen i have that black screen and as you mentioned it was the "startup screen",
the issue even if I waited forever to pause and then I hit the resume button, I got the same black screen and when using (Alt+Tab) the game exiting,
it's my first time writing autohotkey scripts and it works, Yay!
;Duckstation Resume Script
WinExist("ahk_exe duckstation-qt-x64-ReleaseLTCG.exe")
WinActivate ; Use the window found by WinExist.
Send {F12} ; Where F12 is fullscreen toggle button on Duckstation
by the way "F12" is my fullscreen toggle button on Duckstation
