[🐛 Bug]: Selenium ChromeDriver 'DevToolsActivePort file doesn't exist' with Profile Automation

[divyansh335500]

What happened?

When using Selenium ChromeDriver to open and automate tasks with a specific Chrome profile, Chrome opens the profile window but stops responding to automation commands. The URL is not opened and no further progress is made after the browser window appears. This bug started occurring about 5-6 days ago; previously, the same code worked as expected.

Error Message:

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: DevToolsActivePort file doesn't exist

Steps to Reproduce:

1. Use this Python code to attempt opening multiple Chrome profiles with Selenium:

   from selenium import webdriver
   chrome_options = webdriver.ChromeOptions()
   profiles=[33,34,36,37,38,39,40]
   
   def profile(profile_name):
       path='C:\\Users\\Divya\\AppData\\Local\\Google\\Chrome\\User Data\\'
       chrome_options.add_argument(f"user-data-dir={path}")
       chrome_options.add_argument(f'--profile-directory=Profile {profile_name}')
   
   for i in range(7):
       profile(profiles[i])
       web=webdriver.Chrome(options=chrome_options)
       web.maximize_window()
       web.get("https://www.myntra.com/my/address")
       web.quit()

2. Observe that the Chrome profile window opens, but the browser does not navigate to the URL or execute further commands.

Expected behavior: Selenium should successfully attach to the Chrome profile and automate tasks (navigate to URL, etc.) as scripted.

Actual behavior: Chrome opens with the profile, but Selenium is unable to send further commands. The process hangs, and the URL is not loaded.

Additional Information:

• The issue appears when automating with multiple profiles.
• The bug started recently (within the last week).
• Screenshot attached:

What browsers and operating systems are you seeing the problem on?

• Chrome version: 136.0.7103.114
• ChromeDriver version: 136.0.7103.113
• Selenium version: 4.33.0
• Python version: 3.11.9
