Hello Team,

I am making the customize zoom using the zoom sdk environment now I am getting error this code. ZoomServiceOnInitializedChanged function is getting error during the zoom button event.

private void ZoomServiceOnInitializedChanged(object sender,bool initialized)  
{  
[//MessageBox.Show](https://MessageBox.Show)(initialized.ToString());  
try  
{  
if (initialized)  
{  
//VideoDevices=\_zoomService.  
VideoDevices = \_zoomService.EnumerateVideoDevices()?.ToList();  
if (VideoDevices != null && VideoDevices.Count \> 0)  
SelectedVideoDevice = VideoDevices.First();

```
                MicDevices = _zoomService.EnumerateMicDevices()?.ToList();
                if (MicDevices != null && MicDevices.Count > 0)
                    SelectedMicDevice = MicDevices.First();

                SpeakerDevices = _zoomService.EnumerateSpeakerDevices()?.ToList();
                if (SpeakerDevices != null && SpeakerDevices.Count > 0)
                    SelectedSpeakerDevice = SpeakerDevices.First();
            }
        }
        catch(Exception ex)
        {
            string str = ex.Message;
        }
    }

```
