"OSError: exception: access violation reading" when using Tkinter

[archiif]

Here is my code:

import keyboard
import tkinter as tk
from PIL import Image

def show_img(im):
    window = tk.Tk()

    w = h = window.winfo_screenheight() * 0.75
    size = (w, h)
    thumb = im.copy()
    thumb.thumbnail(size, Image.ANTIALIAS)

    ws = window.winfo_screenwidth()
    hs = window.winfo_screenheight()
    x = (ws / 2) - (w / 2)
    y = (hs / 2) - (h / 2)
    window.geometry("%dx%d+%d+%d" % (w, h, x, y))

    img = ImageTk.PhotoImage(thumb)
    panel = tk.Label(window, image=img)
    panel.pack(side="bottom", fill="both", expand="yes")
    window.mainloop()

def on_activate():
    im = Image.new("RGB", (100, 30), color=(73, 109, 137))
    show_img(im)

keyboard.add_hotkey("f4", on_activate, suppress=True)

print("Listening to keyboard events")
keyboard.wait()

After displaying and closing the window generated by Tkinter, this exception occurs:

Exception in thread Thread-1:

    while not GetMessage(msg, 0, 0, 0):

Any solutions or workarounds to this issue? Maybe this: https://github.com/boppreh/keyboard/issues/256 is relevant?

after some testing, I think this error occurs when the listener detects another keyboard event while the on_activate function is still running. A possible work around to this is running any non-instantaneous operations you may have on a different thread.
