"Win and Up Arrow" is shortcut for changing to fullscreen mode, but it does not work properly before clicking window or change input mode to UI or GameAndUI.

probably, Win API caused this issue, and we should call ::ReleaseCapture() after launch. Changing input mode to UI or GameAndUI run this.

Steps to Reproduce
  1. Open any project
  2. Run by Standalone
  3. When the blackout is over and the screen is displayed, press "Win and Up Arrow"

expect : change to fullscreen
result : don't change to fullscreen
