[Python] Error closing tabs with PyChrome -Exception in thread Thread

I have a Python script that uses the pychrome module to open a webpage and get the text of a specific HTML element. The script works correctly and retrieves the text from the element, but I keep encountering the following error after printing the text:

Exception in thread Thread-1 (_recv_loop):

I have already tried several solutions suggested by AI models like ChatGPT and other sources, but none of them resolved the issue.

Here is the full script I am using:

import subprocess
import time
import pychrome

# Start Chrome in remote debugging mode
chrome_path = r"C:\Program Files\Google\Chrome\Application\chrome.exe"
user_data_dir = r"C:\Users\Administrator2\AppData\Local\Google\Chrome\User Data"
remote_debugging_port = 9222

# Command to start Chrome
subprocess.Popen([chrome_path, f"--remote-debugging-port={remote_debugging_port}", f"--user-data-dir={user_data_dir}"])

# Wait a moment to ensure Chrome starts
time.sleep(5)

# Connect to Chrome
browser = pychrome.Browser(url=f"http://127.0.0.1:{remote_debugging_port}")

# Create a new tab
tab = browser.list_tab()[0] # Select the first tab
tab.start()

# Navigate to the page
tab.call_method("Page.navigate", url="here any website")
tab.call_method("Page.enable")

# Wait a moment for the page to load
time.sleep(5) # Adjust the wait time as necessary

# Wait until the desired element appears in the DOM
total_wait_time = 20 # Total wait time in seconds
chunk_wait_time = 5 # Time to wait for each chunk in seconds
elapsed_time = 0

while elapsed_time < total_wait_time:
time.sleep(chunk_wait_time) # Wait for the chunk time
elapsed_time += chunk_wait_time # Increment the elapsed time

# Evaluate the DOM to check if the element is present
element = tab.call_method("Runtime.evaluate", expression='document.querySelector("div.count.ng-star-inserted")')

if 'result' in element and element['result'] is not None:
# If the element is present, get its text
text_content = tab.call_method("Runtime.evaluate", expression='document.querySelector("div.count.ng-star-inserted").innerText')
print(f'Text in <div class="count ng-star-inserted">: {text_content["result"]["value"]}')
break
else:
print("Element not found within 20 seconds. Exiting script.")

# Close the tab properly
tab.stop()


I would appreciate any insights or suggestions to fix this issue.

EDIT: As mentioned, the script works correctly and retrieves the text from the element. The issue occurs when attempting to close the tab.
