Rendering in console app not working if console app is starting as windows service child process

Description
Rendering in console apps works if I start the console app in the context of the current logged in user.
If i start the console app as child process of a Windows service (no UI available) CreateCoreWebView2ControllerAsync does not return.

internal class Program
    {
        private static readonly IntPtr HWND_MESSAGE = new IntPtr(-3);

        [STAThread]
        static void Main(string[] args)
        {
            Test();
            Application.Run();
        }

        static async void Test()
        {
            SynchronizationContext.SetSynchronizationContext(new WindowsFormsSynchronizationContext());
            await Task.Delay(1); // wait for the application loop to start
            var browserEnv = await CoreWebView2Environment.CreateAsync();
            var wvController = await browserEnv.CreateCoreWebView2ControllerAsync(HWND_MESSAGE); // not working in a Windows Service Childprocess
            wvController.Bounds = new System.Drawing.Rectangle(0, 0, 100, 100);
            wvController.CoreWebView2.Navigate("http://localhost/");
            TaskCompletionSource<bool> tsc = new TaskCompletionSource<bool>();
            wvController.CoreWebView2.NavigationCompleted += (s, e) =>
            {
                tsc.SetResult(true);
            };
            await tsc.Task;
            using (FileStream stream = new FileStream("D:\\testImg.png", FileMode.Create))
            {
                await wvController.CoreWebView2.CapturePreviewAsync(CoreWebView2CapturePreviewImageFormat.Png, stream);
            }
            Application.Exit();
        }
    }
