    Hello! I have a weird problem - whenever I'm trying to import my C++ "backend" to QML, the QML GUI doesn't even load.

    I have an application that launches loader.qml from C++, which source is stackview.qml.

    Loader QML:

    import QtQuick
    import QtQuick.Window
    
    Window {
      id: window
      width: 800
      height: 480
      visible: true
      color: "#000000"
      title: qsTr("Test")
    
      Loader {
        id: mainLoader
        anchors {
          left: parent.left
          right: parent.right
          top: parent.top
          bottom: parent.bottom
        }
        source: "stackview.qml"
      }
    }
    

    Stackview QML

    import QtQuick
    import QtQuick.Controls
    
    import MyApp.Backend // If I comment this out, everything works
    
    Item {
      anchors.fill: parent
    
      StackView {
        id: mainStackview
        anchors.fill: parent
        initialItem: "screen_main.qml"    
    
        Connections {
          target: cppStackview
          onChangeScreen: {
            console.log("Screen change to : " + screen_url)
            mainStackview.push(screen_url)
          }
        }
      }
    }
    

    Keep in mind, that I'm using import MyApp.Backend in other QML files and it works fine. I guess it's because it's the first .qml file that's being loaded? There are no logs from Qt on this - it simply shows blank screen.

      Try running your application with the QML_IMPORT_TRACE set to 1 and look at the messages in the console.
