Details on the crash and parts of related Qt sources.

It looks like Origin makers decided to use a QGuiApplication in this service.
As a result it queries available monitors via EnumDisplayMonitors.
Because this runs as a service this is routed to nulldrv_EnumDisplayMonitors
which just returns false without calling the callback.
Therefore Qt's screen_list never gets filled and later a call to
QGuiApplication::primaryScreen()->handle() leads to the crash because
primaryScreen() returns null.
