CaptureVideoAsync always returning null when using Windows Machine

Description

When trying to capture video running the app as Windows Machine, the video capture method does not show the webcam, and immediately returns null.

private async Task OnCaptureVideoClickedAsync()
        {
            if (await Permissions.CheckStatusAsync<Camera>() != PermissionStatus.Granted)
            {
                var result = await Permissions.RequestAsync<Camera>();
                if (result != PermissionStatus.Granted)
                {
                    ToastService.ShowError("You need to grant the camera permission to use this feature");
                    return;
                }
            }
            var video = await MediaPicker.Default.CaptureVideoAsync();
        }

Permissions are set like this

<Capabilities>
    <rescap:Capability Name="runFullTrust" />
    <DeviceCapability Name="location"></DeviceCapability>
	<DeviceCapability Name="webcam" />
    <DeviceCapability Name="microphone" />
  </Capabilities>

Steps to Reproduce

1. Create a MAUI Blazor app
2. Add a button and invoke a method containing. var video = await MediaPicker.Default.CaptureVideoAsync();
3. Configure the permissions as in the description
4. Run the app as Windows Machine.

Seems it is related to this issue and that it’s not a MAUI issue, but instead a WinUI/platform issue https://github.com/dotnet/maui/issues/5849
