I add to my program a QFileDialog window. When I close the file dialog window, the function keep executing the following command but at the end of the function the main window is closed and after the FileDialog.

Here is my program:

class Controller(QtWidgets.QWidget):
    view: View
    model: Model

    def __init__(self, model: Model, view: View):
        super(Controller, self).__init__()


    def open_datalog_folder(self, txt):
        print(txt)
        file_dialog = QFileDialog()
        try:
            directory = file_dialog.getOpenFileName(None, "Select directory")
            # file_dialog.blockSignals(True)
            print ('here')
        except:
            print("fzz")
            pass

When I execute the program, I get the "Here" flag and the the program close. I try to block the signal from my file dialog quit event to avoid to send it to the lain window but it does work.
