When generating a new window immediately after closing the previous one, the above message is generated on the console but the code works fine without any error can you please solve this as some people consider it as an error

[AshhadDevLab]

Description:

This is caused because the window is instantiated to be looped after the initial window has been destroyed. Something like this:

window.destroy()
anotherwindow.mainloop()

Solution:

To avoid this you can make use of CTkTopLevel or create multiple CTkFrame widgets instead of windows and move back and fourth in them.

If this answers your question mark it as solved!

I am getting this message in the console but the application still works fine but if the message comes more then 8-10 times then the application crashes

[AshhadDevLab]

Did you try my solution?

[kohinoor12]

Yes that issue is resolved now, in my application I have a popup window that works as a preloader when different functions been called that time I'm getting the above message

[AshhadDevLab]

instead of destroying the window withdraw it first and after the other window is loaded destroy it

[AshhadDevLab]

can you somehow give a minimal reproducible code
