    Description

      Whenever I attempt to open a UI file in the Designer using the fallback layer there is an error about the quick-emulation layer having crashed. The project I am trying to edit is a Qt 5.12 based project. The UI is simply part of one of the templates with dimensions added:

      import QtQuick 2.12
import QtQuick.Controls 2.5

Page {
    width: 600
    height: 1024

    header: Label {
        text: qsTr("Page 2")
        font.pixelSize: Qt.application.font.pixelSize * 2
        padding: 10
    }

    Label {
        text: qsTr("You are on Page 2.")
        anchors.centerIn: parent
    }
}

      It used to work and for some reason it doesn't now anymore.

       

      I installed the qt creator debug package but seems like I am still missing some debug symbols:
