This is a MCVE:

import sys
from PyQt6.QtCore import QObject, QThread, pyqtSignal, pyqtSlot
from PyQt6.QtWidgets import QApplication

class Task(QObject):
    @pyqtSlot()
    def start(self):
        print("task started")

class Controller(QObject):
    startTask = pyqtSignal()

    def __init__(self):
       super().__init__()
       self.workerThread = QThread()
       self.workerThread.start()

    def start(self):
        task = Task()
        task.moveToThread(self.workerThread)
        self.startTask.connect(task.start)
        self.startTask.emit()
        print("startTask signal sent")

if __name__ == "__main__":
    app = QApplication(sys.argv)
    controller = Controller()
    controller.start()
    sys.exit(app.exec())

When I run this code, "task started" is not printed. Why?
