I need to disable the button until the function is completed.

   self.button_apply.clicked.connect(self.apply_clicked)

 def apply_clicked(self):
        """Events when accept button is pushed""" 
        self.button_apply.setEnabled(False)
                
        self.text_edit.append("button clicked")   
        QTimer.singleShot(1000, lambda: self.create_credentials_folder(self.samba_path_credentials))        
        self.button_apply.setEnabled(True)

It is not disabling the button.
The process should be: I click on button -> it gets disabled until all processes finished, but it is not disabling.
