bug
Application crashes when running screen share on Windows

To Reproduce
Get the sources of the video:

 final sources = await desktopCapturer.getSources(
        types: [
          SourceType.Screen,
          SourceType.Window,
        ],
      );

Start screen sharing:

Future<void> publishScreen(String source) async {
    room?.localParticipant?.setScreenShareEnabled(true,
        captureScreenAudio: true,
        screenShareCaptureOptions: ScreenShareCaptureOptions(
            sourceId: source,
            captureScreenAudio: true,
            params: VideoParameters(
              dimensions: VideoDimensions(1920, 1080),
              encoding: VideoEncoding(
                maxBitrate: 5000 * 1000,
                maxFramerate: 60,
              ),
            )));
  }

The application simply closes without any messages.

Expected behavior
Starting a screen sharing (works great on Mac)
