Created attachment 78307
  --> https://bugs.winehq.org/attachment.cgi?id=78307
patch

Confirming

After adding a stub, crashes into more undocumented functions like
ntdll.SbSelectProcedure and user32.IsThreadDesktopComposited follow which is
weird.

Turns out there's a dwmapi.dll in the program's directory, which is picked up.
The attached patch makes the application start.
