My python file works perfectly in cmd, but doesn't work in IDLE

Question

I made a rock-paper-scissors game using the pygame module in python. It runs perfectly well in the IDE(PyCharm) and the command prompt and everything works (including the cross button), but when I press the cross-button of the GUI window when the code is running in IDLE, the game crashes.

I don't get any error messages , but the game freezes after I press the cross button once; then I cant give any more inputs to the window, but the cross button still glows red when I hover over it, but if I press it again (2nd time), then the cross button stops glowing red and the game remains frozen.

This is the complete code. I commented on the part of the code which runs perfectly in cmd but doesn't run in IDLE (see just a few lines below the #Game-loop comment):-

import random
import pygame

# Initialize the pygame
pygame.init()

# create the screen
screen = pygame.display.set_mode((800, 600))

# Title and icon
pygame.display.set_caption("RPS Pro")
icon = pygame.image.load('icon.png')
pygame.display.set_icon(icon)

# Images
rock = pygame.image.load('rock.png')
paper = pygame.image.load('paper.png')
scissors = pygame.image.load('scissors.png')
swords = pygame.image.load('swords.png')

x_swords = 330
y_swords = 250
x_UI = 80
y_UI = 250
x_player = 650
y_player = 250

screen.fill((255, 215, 0))

UI_score = 0
player_score = 0

#Game-loop

            running = False #this doesnt seem to work in python IDLE but works perfectly in cmd and PyCharm

        if event.type == pygame.KEYDOWN:

            font = pygame.font.SysFont('comicsans', 30, False, False)

            UI_value = random.randint(1, 3)

            if UI_value == 1 and event.key == pygame.K_r:

    pygame.display.update()

Please let me know if you have any further inquiries about my problem. Thanks in advance!

pygame FAQ has offered an solution for In IDLE why does the Pygame window not close correctly? . You need to add pygame.quit() at the end line of your code.

#Game-loop
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False #this doesnt seem to work in python IDLE but works perfectly in cmd and PyCharm

    pygame.display.update()

pygame.quit()
