Function call is missing argument. Building Crash Report Client. SlateApplication.cpp:3822:65: error: too few arguments to function call, expected 3, have 2

No Clue if I did this right, but possible fix is on line 3822:
Crash report client builds without complaint at least so far.

SWindow* SlateWindow = WidgetWindow.Get(); 
Renderer->PrepareToTakeScreenshot(ScreenshotRect, &OutColorData, SlateWindow);
