QImage + iOS open from locale path

[Lynx]

Hello, I'm write application for iOS. I get image path via QML FileDialog ("file:assets-library://asset/asset.JPG%3Fid=C6E6...77E9&ext=JPG")) and send to C++, I get message "Image not load". what I do wrong ?
qml:

    FileDialog {
        id: fileDialog
        title: "Please choose a file"
        folder:StandardPaths.standardLocations(StandardPaths.PicturesLocation)[2]//shortcuts.home
        selectExisting: true
        onAccepted: {
            //console.log(file)
            imageProcessor.processImage_file(fileDialog.file)
            fileDialog.close()
        }
        onRejected: {
            console.log("Canceled")
            fileDialog.close()
        }
    }

C++:

void ImageProcessor::processImage_file(const QString &path)
{
    QString assetsPath=path;
    QImage myImage;
    QUrl url(assetsPath);
    assetsPath = url.toLocalFile();
    myImage.load(assetsPath);
    if( !myImage.isNull()) 
    {
              //........
    }
    else qDebug()<<"Image not load";

I have same issue, I used Filedialog as below:

 FileDialog {
                            id: fileOpenDialog

                            title: "Select an image file"
                            folder: Qt.platform.os == "ios" ? shortcuts.pictures :shortcuts.documents
                            nameFilters: [ "Image files (*.png *.jpeg *.jpg)" ]
                            onAccepted: {
                                console.log(fileOpenDialog.fileUrl);
                                avatar.source = fileOpenDialog.fileUrl;
                          }                               
}

But when I try to choose an image from iOS device, the path is
qml: file:assets-library://asset/asset.HEIC%3Fid=CC95F08C-88C3-4012-9D6D-64A413D254B3&ext=HEIC
Then I can't open it in Image as set avatar.source = fileOpenDialog.fileUrl;
Anyone have solution?

Then I try get a PNG file instead HEIC, but I still got error, and there is a strange thing, this is my log:

qml: file:assets-library://asset/asset.PNG%3Fid=C8465D9C-B920-4400-9C92-2B34ADD5127C&ext=PNG
qrc:/pages/UserInfoPopUp.qml:156:21: QML Image: Error decoding: file:assets-library://asset/asset@3x.PNG%3Fid=C8465D9C-B920-4400-9C92-2B34ADD5127C&ext=PNG: Unsupported image format

I don't know why as log, I passed asset.PNG but actually image got asset@3x.PNG
Anyone has idea and solution for these?
