Streamed Videos Hang While Sharing

I recently have encountered streamed videos hanging while sharing (even without meeting participants).  I'm using Windows 11 (updated w/ 24H2 installed) and Zoom Workplace 6.3.11. The videos display just fine when not sharing. This happens using my laptop display or my UHD TV/monitor. Lenovo app used to check all drivers up to date. Rebooting PC has no impact on problem.  Nothing obvious to me while watching performance in Task Manager and videos hang.

I have no problem sharing the same videos using my iPad Mini (6th Generation).

Any help would be appreciated.
