Black rectangles when sharing

[mathsbrain]

I teach online using Zoom.  I want to be able to share an application on my screen for my students to see but then work on other windows while they continue to see the application.  I don't want to just share the whole screen, as this means that the application that the students are working on will vanish from view or be obscured by other windows.  I was able to do this with no problems until a recent update of Zoom.  I get the message "Please move this window from the shared application" and students see black rectangles on their screens.  If I maximise the window that I'm not sharing, the students' screens simply turn black.  It's exasperating that this was working fine until Zoom was updated.

I'm using a PC with the following details:

Windows Version

Windows 11 Pro, last updated 7/9/24, OS Builds 22621.3880 and 22631.3880

Graphics Card

Intel (R), Iris (R), Xe Graphics

Driver: 31.0.101.5590

Driver date: 10/6/24

Zoom Version

6.1.5

What can I do to solve this problem?

This is a recurring issue with multiple Windows users at our firm starting about 2 weeks ago.  Have tried multiple 'fixes' noted in previous posts, to no avail. Any solutions?
