5.15.2 still includes the possibility for using QtQuick.Controls 1.1 (1.4) which still have the `onCurrentIndexChanged` function. Your change made it so the event handler is no longer called, but is...

Muse Hub is not MuseScore and entirely optional, just like any VST is entirely optional or any soundfont is. In the meantime, the Muse Hub team has their own support...
