Cannot open video from Content panel to full-screen preview

When a video clip, say a .mp4 file, is selected from the list in my Content panel, and I hit spacebar to play it in full-screen mode, nothing happens. This is on my MacBook Pro 16-inch Nov 2023 running Sequoia 15.2.

I can work around this by selecting a static image, say a .jpg file, that is also in the list in my Content panel, hit spacebar to display it in full-screen mode, and then use the up-arrow or down-arrow to get to the .mp4 file. The video then plays in full-screen mode as expected.
