Cannot build OSApp in Debug Mode since the move to Qt 6.3.0

Issue overview

Current Behavior

I get a linked error, which is probably indicative of an actual issue in the code.

/usr/bin/ld: Products/libopenstudio_lib.a(ApplyMeasureNowDialog.cpp.o): in function `QtPrivate::assertObjectType<openstudio::OpenStudioApp>(QObject*)::{lambda(QObject*)#3}::operator()(QObject*) const':

Possible Solution

There's probably a virtual function that's missing a definition in the current translation unit (TU)
