m_hwndHotkey = ::CreateWindow(wndClass.lpszClassName, nullptr, 0, 0, 0, 0, 0, HWND_MESSAGE, nullptr, wndClass.hInstance, this);

So you’re not hooking the WinUI3 window’s message loop, you’re just creating an additional (invisible) window. Hmmm.

Actually maybe this is sub-classing. Better just copy paste.

I had posted a sample in C#, using standard subclassing : https://github.com/castorix/WinUI3_DesktopDuplication/blob/master/MainWindow.xaml.cs
