CTkOptionMenu & CTkComboBox throw error during display scale change after being destroyed

[Franzyd]

Tested on Windows 10 The two dropdown menu widgets, CTkOptionMenu and CTkComboBox throw a TcLError: invalid command name when the window's scale changes after being destroyed. Tested scenarios are changing the display scale in Windows settings and moving it to another monitor with a different display scale.

import customtkinter

app = customtkinter.CTk()
app.geometry("400x150")

options = customtkinter.CTkOptionMenu(app, values=["1", "2", "3"])
options.pack() //layout manager is irrelevant

delete = customtkinter.CTkButton(app, text="Delete", command= lambda: options.destroy())
delete.pack()

app.mainloop()

Clicking the button to destroy the dropdown widget and then changing the display scale throws:

_tkinter.TclError: invalid command name ".!ctkcombobox.!dropdownmenu"

After that the window is still interactable but semitransparent and doesn't rescale anymore:

Did you try any workaround to fix this?
