How to fix pysimplegui error?

Question

Python

I'm working on creating a graphical interface. I'm working with pysimplegui for the first time and I'm not completely sure about the correctness of the code, but it seems to have worked before. As far as I understand the essence of the error is that you cannot use the same element in different layouts. Here's the text of the error just in case: UserWarning: *** YOU ARE ATTEMPTING TO RESUSE AN ELEMENT IN YOUR LAYOUT! Once placed in a layout, an element cannot be used in another layout. ***.
Swears if you close the page, and then try to open it again.
Directly problematic section of code

if event == "Отмена":
            window.close()
            window = sg.Window("Меню", menu_admin)
            wnd = "menu_admin"
