У меня есть этот код для переключения между меню

    sys.exit(app.exec_())

все работает хорошо, пока я не выключу его (само) почему код так нестабилен?

проблема

мне нужно

Я пытался работать с self.menu_group_ani, используя clear () или, если что-то, что я делаю, код не работает правильно, clicked.connect также не дал желаемого результата. Как это исправить?
