更新图像中的源时出错

我编写了以下代码来在 WPF 窗口中显示客户端发送的图像：

namespace ScreenStream
{
    public partial class MainWindow : Window
    {
        private TcpListener _listener;

        public MainWindow()
        {
            InitializeComponent();
            StartServer();
        }

        private async void StartServer()
        {
            _listener = new TcpListener(IPAddress.Any, 12345);
            _listener.Start();

            while (true)
            {
                var client = await _listener.AcceptTcpClientAsync();
                _ = Task.Run(() => HandleClient(client));
            }
        }

        private async Task HandleClient(TcpClient client)
        {
            using (var networkStream = client.GetStream())
            using (var memoryStream = new MemoryStream())
            {
                await networkStream.CopyToAsync(memoryStream);
                memoryStream.Position = 0;

                var bitmapImage = new BitmapImage();
                bitmapImage.BeginInit();
                bitmapImage.StreamSource = memoryStream;
                bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
                bitmapImage.EndInit();

                Dispatcher.Invoke(() =>
                {
                    ScreenshotImage.Source = bitmapImage;
                });
            }
            client.Close();
        }

        protected override void OnClosed(EventArgs e)
        {
            _listener?.Stop();
            base.OnClosed(e);
        }
    }
}

问题是ScreenshotImage.Source = bitmapImage;它会抛出错误System.InvalidOperationException: 'The calling thread cannot access this object because a different thread owns it.'。

我尝试以不同的方式声明它纯粹是无意义的Dispatcher，例如：

this.Dispatcher.Invoke(() =>
{
    ScreenshotImage.Source = bitmapImage;
});

或者

Application.Current.Dispatcher.Invoke(() =>
{
    ScreenshotImage.Source = bitmapImage;
});

但结果总是相同的，原则上这并不奇怪，而且我对如何解决问题没有任何其他想法，我用谷歌搜索了它，他们写到的任何地方都可以通过简单地添加来修复错误Dispatcher.Invoke，但是对于出于某种原因它对我没有帮助
