QtQuick3D RuntimeLoader with windeployqt

primitiveDataType

Hello,

Im having aproblem with the RuntimeLoader from QtQuick3D.

Im trying to load a GLTF file while the programm is running, which works as long as I do not deploy the Programm with windeployqt
This is my RuntimeLoader code:

        RuntimeLoader {
            id: importNode
            scale: Qt.vector3d(helper.scaleFactor, helper.scaleFactor, helper.scaleFactor)
            source: importUrl
            onBoundsChanged: helper.updateBounds(bounds)
        }

FileDialog:

    FileDialog {
        id: fileDialog
        nameFilters: ["glTF files (*.gltf *.glb)", "All files (*)"]
        onAccepted: {
            console.log(file)
            importUrl = file
            openJsonFile(file)
        }
        Settings {
            id: fileDialogSettings
            category: "QtQuick3D.Examples.RuntimeLoader"
            property alias folder: fileDialog.folder
        }
    }

As soon as I select the file from a dialog it opens without any problem.
But after deploying it I get assertion errors and the programm exists without any message

Removing just the RuntimeLoader fixes the problem but that isnt realy an option, since the whole point is to render the gltf

Any idea waht I am doing wrong?
Thanks
