Issues with making a video. Desktop

whenever I try to preview a video I end up with a preview box bigger than my screen that I can’t close since it seems the controls are outside the area of my screen.

I end up having to end the process as I can no longer interact with the program.

on a side note when I export a print-quality version it sometimes hangs indefinitely with the stop button greyed out…

I also encountered such a problem, alt + f4 helped me, and this is not a joke, with such a combination, only the window that goes beyond the monitor is closed, without closing the program itself

sad that this is still a problem 8 months later…
