python - Unhandled exception in listener callback computer stopped program after waking up from sleep mode

Question

I am writing a python script to put my computer into sleep mode, whenever I press the hotkey cmd + enter which is the same as the windows key and the enter key at the same time. The program puts the computer into sleep mode just fine, but when I wake it up again and unlock the device an error occurred and the program stopped due to this error:

Unhandled exception in listener callback

My script just pressed the shortcut cmd + d which goes straight to the desktop and then presses alt + f4 followed by enter.

The Code:

from pynput import keyboard
import time
import pyautogui

# The key combination to check
COMBINATIONS = [
    {keyboard.Key.cmd, keyboard.Key.enter}
]

current = set()

def execute():
    print("Shortcut pressed")
    pyautogui.hotkey('win', 'd')
    pyautogui.hotkey('alt', 'f4')
    time.sleep(0.2)
    pyautogui.keyDown('up')
    pyautogui.keyUp('up')
    time.sleep(0.1)
    pyautogui.keyDown('enter')
def on_press(key):
    if any([key in COMBO for COMBO in COMBINATIONS]):
        current.add(key)
        if any(all(k in current for k in COMBO) for COMBO in COMBINATIONS):
            execute()
'''
def on_release(key):    
    if any([key in COMBO for COMBO in COMBINATIONS]):
        current.remove(key)
''' 

with keyboard.Listener(on_press=on_press) as listener:
    listener.join()

So the problem is that the program ends its execution when the pc wakes up from sleep mode.

Question:
How can I avoid that the program throws an exception after waking up from sleep mode or is it impossible because every running prcess gets stopped when I put the system into standy?
