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
Traceback (most recent call last):
