Why is my mainloop not working in tkinter?

Question

I have a python3 code below:

import multiprocessing as pr
from multiprocessing.managers import BaseManager
import tkinter as tk

def func(root):
    root.mainloop()

BaseManager.register('Tk', tk.Tk)
manager = BaseManager()
manager.start()
inst = manager.Tk()

# print('dd',inst)

process = pr.Process(target=func,args=[inst])
process.start()
process.join()

In the above code, I have created a shared Tk object and I invoked its mainloop method from another process. But it's not working.

It should create a window. What wrong is going on?

I need help !!!

You can't share tkinter objects between processes. Tkinter is a wrapper around an embedded tcl/tk interpreter, and that embedded tcl/tk interpreter cannot span more than one thread or process.
