Starting from macOS 10.15, some users may experience an issue with the sharing permission compatibility. It can be fixed in the following steps:
Go to System Preferences > Security & Privacy > Privacy.
Deselect the option. If you are using VooV Meeting, you will be asked whether to exit. Click Later, and then select the option again. If you are using VooV Meeting, you will be asked whether to exit again. Then, click Later and check whether the screen can be shared.
If the problem persists, try restarting the computer.
If the problem still persists, right click and select Show in Finder, delete the VooV Meeting app, and check whether the app is still displayed in the list.

If so, check whether the following message is displayed on the topbar:
Solution: the problem will be fixed when the sharer removes the occlusion of the shared window.
Check whether the shared window is occluded by another window. For some device models (for example, Windows 7 PC), the occluded part of the window will be displayed as a black or gray screen on the viewer's side.
At this time, the sharer's topbar will display "Window obscured. Bring your shared window to the front.". This helps determine whether the problem is caused by window occlusion, and if this is the case, the problem can be fixed when the sharer removes the occlusion of the shared window.
If the problem is caused by other issues, contact Online Support for assistance.
