How to fix selenium "DevToolsActivePort file doesn't exist" exception in Python

Question

When I use both arguments --headless and user-data-dir. Selenium raise selenium.common.exceptions.WebDriverException: Message: unknown error: DevToolsActivePort file doesn't exist exception. If only 1 of them is used, then everything works as needs.

I tried to swap arguments and remove some of them.
Specified the full path to chromedriver.exe.
None of this helped.

chromeOptions.add_argument(“–disable-dev-shm-using”) DIDN’T HELP ME.

login = "test"
chromeOptions = webdriver.ChromeOptions() 
chromeOptions.add_experimental_option("prefs", {"profile.managed_default_content_settings.images": 2}) 
chromeOptions.add_argument("--no-sandbox") 
chromeOptions.add_argument("--disable-setuid-sandbox") 
chromeOptions.add_argument("--disable-dev-shm-using") 
chromeOptions.add_argument("--disable-extensions") 
chromeOptions.add_argument("--disable-gpu") 
chromeOptions.add_argument("start-maximized") 
chromeOptions.add_argument("disable-infobars") 
chromeOptions.add_argument("--headless") 
chromeOptions.add_argument(r"user-data-dir=.cookies\" + login) 
b = webdriver.Chrome(chrome_options=chromeOptions) 
b.get("https://google.com/") 
b.quit()

I solve it by adding an argument --remote-debugging-port=<port>

chromeOptions = webdriver.ChromeOptions() 
chromeOptions.add_experimental_option("prefs", {"profile.managed_default_content_settings.images": 2}) 
chromeOptions.add_argument("--no-sandbox") 
chromeOptions.add_argument("--disable-setuid-sandbox") 

chromeOptions.add_argument("--remote-debugging-port=9222")  # this

chromeOptions.add_argument("--disable-dev-shm-using") 
chromeOptions.add_argument("--disable-extensions") 
chromeOptions.add_argument("--disable-gpu") 
chromeOptions.add_argument("start-maximized") 
chromeOptions.add_argument("disable-infobars")
chromeOptions.add_argument(r"user-data-dir=.cookies\test") 

b = webdriver.Chrome(chrome_options=chromeOptions) 
b.get("https://google.com/") 
b.quit()
