After the `self.destroy()` code is activated, something appears on the console as in the picture. What is this? 

`self.label_3 = customtkinter.CTkLabel(master=self.frame, text="Register.", cursor="hand2") self.label_3.place(relx=0.5, rely=0.84, anchor=tkinter.CENTER) self.label_3.bind("", lambda e: self.openUrl)` Why didn't this code work for me? I click on the text but it doesn't work
