[Tkinter] Error when closing the main window with destroy

[TomasSanchexx]

Hi, I have a problem. I'm trying to close the main window when logging in, with destroy(), but it throws me an error, why? what am I doing wrong? How can I solve it? Any additional information would be appreciated.
The error that I get when I press the button and want to close the window is the following:

Exception in Tkinter callback

Post the entire error trace please.

Where is login finding self.root? There is no root in login to destroy.
