Ubuntu – Selenium: probably user data directory is already in use, please specify a unique value for –user-data-dir argument, or don't use –user-data-dir

I’m using Selenium in github action.

Nginx, MySQL, Java containers are up then pytest runs and causes error despite of not using --user-data-dir option.

probably user data directory is already in use, please specify a unique value for --user-data-dir argument, or don't use --user-data-dir

In error log, Selenium points there.

    @pytest.fixture(scope="module")
    def driver(request):
        browser = request.config.getoption("browser")
        if browser == "chrome":
            option = chromeOptions()
            option.add_argument("--headless")
            option.add_argument("--no-sandbox")
            option.add_argument("--disable-dev-shm-usage")
>           driver = webdriver.Chrome(options=option)
test/conftest.py:16: 

And stack trace only shows up

Chrome version:

• Google Chrome for Testing 132.0.6834.83
• ChromeDriver 132.0.6834.83

What I tried is:

• set option.add_argument("--user-data-dir=/tmp/chrome-user-data")
• downgrade ubuntu from 24 to 22
• check chrome and chrome driver version

I have no idea to resolve it… I need your help.
