--- Comment #9 from Louis Lenders xerox.xerox2000x@gmail.com --- Looks like it cannot load QtWebEngineCore.
GRRRRR, Spent 20 minutes to scroll through debuglog and then found this:

Just exporting RaiseFailFastException makes the application start. Really time for to add a stub for this one, would have saved some time...
