Error "The group or resource is not in the correct state to perform the requested operation" when doing WebView2.TrySuspendAsync

I basically need to pause a video when the WebView2 control loses its visibility.
What I did was this:

 /*********************************************************************/
 private async void SuspendWebView2(WebView2 webView2 )
 {
     bool bRes = await webView2.CoreWebView2.TrySuspendAsync();
 }
 /*********************************************************************/
 private void WebCtrl_VisibleChanged(object sender, EventArgs e)
 {
     WebView2 webView2 = (WebView2)sender;
     if (webView2.Visible == false && webView2.CoreWebView2.IsDocumentPlayingAudio )
     {
          webView2.CoreWebView2.IsMuted = true;
         SuspendWebView2(webView2);
     }
     else if (webView2.Visible == true && webView2.CoreWebView2.IsDocumentPlayingAudio )
     {
         webView2.CoreWebView2.IsMuted = false;
         webView2.CoreWebView2.Resume();
     }
 }

But I get:
System.InvalidOperationException: CoreWebView2 members cannot be accessed after the WebView2 control is disposed. ---> System.Runtime.InteropServices.COMException: The group or resource is not in the correct state to perform the requested operation. (Exception from HRESULT: 0x8007139F)

I tried a lot of things including hiding or showing the control (sometimes it works but it is not the same all the time), setting a timer and doing it few seconds after and so on....
