Unfortunately, that's not true. There is something else that can cause this, but what I am not sure. On occasion, my own background is not available in a meeting, and I get the OPs same message "Virtual Background has been Disabled", but I am the only one in the meeting whose background doesn't work. When I join the next meeting, my background starts working again. It's not that I am not running the latest version, or that the application is corrupt, because if it was, it wouldn't work in any meeting! There is a bug that causes this and Zoom haven't fixed it yet.
