Video

[LadyFuchsia]

Despite working OK elsewhere, my video is not displaying on Zoom. Having been working fine from 2020 up to a few days ago, Zoom is now saying: "Failed to start video. Please select another video camera ... ".

It displays OK when I go into Zoom [on the preview screen], so the camera itself is not at fault, but when I click on the "Join" button the video disappears and I get that message.

I've tried uninstalling and re-installing Zoom.
My PC tells me the drivers are up to date.
No other application is using the camera.
The camera permissions are ON.
BitDefender allows camera access to Zoom.
I have a basic Zoom account, but only ever join the meetings of others.
I am using a PC with Windows 10 64-bit
USB Video device.
Can anyone help a desperate old lady? I don't know where to turn.

I also haven't a clue if I've chosen the right "Location" from the dropdown list.
