Did you start with the Debian packages or did you package from

It would be somewhat important to know what parameters to
createSubWindow() trigger the assertion.

Are those your changes already? On my machine
linphone-desktop-4.2.5/linphone-app/ui/views/App/Settings/SettingsAudio.qml
contains this line:
...
import QtQuick.Controls 2.7 as Core
...
Which is strange because QtQuick.Controls 2.5 and 2.7 were never
released/never existed: According to the version list
<https://doc.qt.io/qt-5/qtquickcontrols-index.html#versions> there was
a version jump from 2.4 (Qt 5.11) to 2.12 (Qt 5.12), so they probably
were development versions. If you haven't already, it could be worth
a try to just lower these version numbers to "2.4", compile and see
what happens. If it doesn't build, though, you'd have to patch the
necessary features out yourself.
