Where is my menu bar?

Hi, I'm missing my top menu bar. Anyone seen it?
See screenshot attached.

How did you figure this out?

I've also had the menu bar disappear and I can't find a way to restore it.

Are you in Full Screen Window mode?

At this point I'm not sure what "full screen mode" means.

I now have access to my menu bar because I took the nuclear option: I completely uninstalled Resolve and reinstalled it. So I now have menus again.

However, I'm stuck with another problem, which is that the UI occupies 100% of my screen.

But this probably isn't the same thing as "full screen mode".
With menus restored I can now see a button with the title "Full Screen".

If I hit it, the UI doesn't stop occupying 100% of the screen. Instead, the UI changes state: it now looks like video player which still occupies 100% of the screen.

So the good news is that I now have access to menus.
The bad new is that I don't have easy access to any programs other than Resolve.

Mac or PC?
