Screen share problem with videos - is it a glitch?

After recent Zoom upgrades, in early January 2023, I suddenly was unable to share a video clip using share screen if I tried to share it full screen. Automatically the screen share was paused, without my doing anything and even when I tried to unpause it in the panel across the top it would not undue.  

I can use sharescreen to share a video clip on Zoom if I don't try to make it full screen. But every time I try to go full screen with the video clip I get the same problem.

Could it be a Mac issue?  I have a smallish Mac screen display size of 13.3 inches. Could that be a problem? It was fine before - until the 2023 Zoom updates. Currently using Mac OS Ventura 13.2.
