[Python] issue with python script to reduce jpm images

I'm on windows 11, using a Python script to compress JPG images recursively in a folder and its subfolders. The script uses the Pillow library and is designed to reduce image quality by 70% while replacing the original files. However, I'm encountering an issue where the script suddenly stops processing in the middle of execution without any error message. Here's the script I'm using:

import os
from PIL import Image

def compress_images(directory, quality):
"""
Recursively compresses all JPG images in a directory and its subdirectories.

Args:
directory (str): Path of the directory to process
quality (int): Quality of the compressed image (1-100)
"""
# Convert path to absolute format
directory = os.path.abspath(directory)

# Counter for processed images
processed = 0

# Iterate through all files in directory and subdirectories
for root, dirs, files in os.walk(directory):
for filename in files:
# Check if file is a JPG image
if filename.lower().endswith(('.jpg', '.jpeg')):
filepath = os.path.join(root, filename)
try:
# Open the image
with Image.open(filepath) as img:
# Check if image is in RGB mode
if img.mode in ('RGBA', 'P'):
img = img.convert('RGB')

# Save compressed image overwriting the original
img.save(filepath, 'JPEG', quality=quality, optimize=True)

processed += 1
print(f"Compressed: {filepath}")

except Exception as e:
print(f"Error processing {filepath}: {str(e)}")

return processed

# Directory path to process
directory = r"C:\Users\TESTA LORENZO\Desktop\foto camion"

# Calculate quality (30% of original = 70% reduction)
quality = 30

# Run compression
try:
num_processed = compress_images(directory, quality)
print(f"\nCompression completed!")
print(f"Number of images processed: {num_processed}")
except Exception as e:
print(f"An error occurred: {str(e)}")



The script works fine initially and processes some images, but then it just stops at a random point. No error messages are displayed nor useful logs, it just freezes and doesn't continue processing the remaining images.

I tried adding more logs but no errors appear. It also doesn't use much memory while working

Any idea why it might be stopping unexpectedly?
