I just tested joining a zoom meeting in our WebView2Sample app and it seemed to work as expected. However, I did have to accept some device permissions from the page. Can you try listening for CoreWebView2.PermissionRequested events, and allowing the necessary permissions? For example, Camera, Microphone, etc.
https://learn.microsoft.com/en-us/dotnet/api/microsoft.web.webview2.core.corewebview2.permissionrequested?view=webview2-dotnet-1.0.2903.40
https://learn.microsoft.com/en-us/dotnet/api/microsoft.web.webview2.core.corewebview2permissionkind?view=webview2-dotnet-1.0.2903.40

Please confirm the event is getting fired. Let me know if that doesn't resolve the issue. Thanks!
