I encountered a problem where, after playing the game (Guilty Gear X2) the image did not disappear from the dock so i used Force Quit. After that when i tried to open it again, it jumped a bit and then vanished (see the picture).
after that i moved the folder to desktop and in there the game worked normally, but when i open it in Applications it won't open.

I would like to open it from Applications again and know why the game did not disappear from the dock.
