QQmlApplicationEngine::load() no longer works with string argument

import sys
import os
from PySide6.QtCore import QUrl

from PySide6.QtGui import QGuiApplication, QIcon
from PySide6.QtQml import QQmlApplicationEngine

if __name__ == "__main__":
    app = QGuiApplication([])
    app.setApplicationName("Test")

    engine = QQmlApplicationEngine()

    path = os.path.dirname( os.path.realpath(__file__) )

    qml_file_path = os.path.join(path, "qml","main2.qml")
    qml_file_url = QUrl.fromLocalFile( qml_file_path )
    engine.load( qml_file_url )

    if not engine.rootObjects():
        sys.exit(-1)

    sys.exit( app.exec() )
