[Tkinter] Top Level Window - from tkinter import *

[francisco_neves2020]

Hi guys, my main programs are based a lot of from subprocess call, but that is giving me problems (it doesn't matter why). I think i could write any code creating a new Top Level Window, but as you will see below, the main issue is from tkinter import * is not allowed. The new tkinter window code is only required that module. If i remove it, it will show only a window with a small, looks like a off button in the middle. And nothing of the remaining code. How can i make it work?
