can't see others' shared screens

Hi, Everyone,

When I'm in a Zoom meeting, I am unable to see screen shared by other meeting members.

This problem started within the past month.  Last night, I was unable to see the screens shared separately by two other members.   I'm on a Windows 11 computer using the Zoom Workplace app version 6.0.11.

I've search through the Settings, but I can't see what setting should be changed to fix this problem. 

I would appreciate any help you can provide. 

Thank you very muchj!
