MainWindow in second thread

Question

I have a problem with opening a MainWindow in a second thread in my python app. I have an Application as default menu and i want to control it by mouse and voice. To do it I need to create an object of MainWindow in my SpeechRecognition class and i need to do it in a thread. I was trying to do it like here: https://realpython.com/python-pyqt-qthread/?fbclid=IwAR10gvY4I4nmRrifpvLM_zykWimMIc8hjUj_0-1epMT4ccSwrLxEwN2jtH4

but when i create a MainWindow thread the window is freezed and can click nothing.

class Recognizer(QObject):

    def run(self):
        self.run_Thread()
        while(True):
            #RECOGNITION FUNCTIONS

    def run_Thread(self):
        self.thread = QThread()

        self.menu = MainWindow()

        self.menu.moveToThread(self.thread)
        self.thread.started.connect(self.menu.run)
        self.menu.finished.connect(self.thread.quit)
        self.menu.finished.connect(self.menu.deleteLater)
        self.thread.finished.connect(self.thread.deleteLater)

        self.thread.start()

class MainWindow(QObject):
    finished = pyqtSignal()
    progress = pyqtSignal(int)
    #REST OF CODE

I don't know how to do it properly.
