New Teams Update

When I upgraded to the latest version of MS Teams, I encountered a problem. During an online presentation with a client, when I played a demo video and shared it with computer audio, the volume suddenly decreased.

Despite checking multiple times, the issue persisted. Eventually, I had to uninstall the new version of MS Teams, reinstall the old one, and revert to its usage. If any of you have experienced a similar issue, please share your insights.
