    Description

      After I changed code from:

      const popupComponent = Qt.createComponent("qrc:/map_tab/RoutePointContextMenu.qml");
const routePointContextMenu = popupComponent.createObject(...);

      to

      Component {
  id: routePointContextMenuC
  RoutePointContextMenu {}
}

const routePointContextMenu = routePointContextMenuC.createObject(...);

      My project starts crashes when I create RoutePointContextMenu (it inherits RoutePointContextMenu) and and remove element from ListView (this action called from RoutePointContextMenu).

      But it crashes only when QML Debugger active, in all other cases, even when I build my project and Qt with sanitizers all works just fine.

      The backtrace looks the same as QTBUG-63919 , here is backtrace:
