quit method in python unittests raises ConnectionResetError using Selenium

I have a class for Integration Test using Selenium for Chrome Webdriver like this

LoginTest.py
class LoginTest(StaticLiveServerTestCase):
    browser = CommonTest.set_up_webdriver()
    wait = WebDriverWait(browser, 20)

    @classmethod
    def setUpClass(cls):
        super(LoginTest, cls).setUpClass()
        cls.browser.maximize_window()
        cls.browser_url = cls.live_server_url
        cls.browser.get(cls.browser_url)

    @classmethod
    def tearDownClass(cls):
        super(LoginTest, cls).tearDownClass()
        time.sleep(3)
        cls.browser.quit() # Error here

    def setUp(self):
        super(LoginTest, self).setUp()
        ...

    def tearDown(self):
        super(LoginTest, self).tearDown()

CommonTest.py
class CommonTest:
    @staticmethod
    def set_up_webdriver():
        options = webdriver.chrome.options.Options()
        options.add_argument("--disable-dev-shm-usage")
        options.add_argument("--no-sandbox")

        return webdriver.Chrome(executable_path=Environment.CHROME_DRIVER_WINDOWS_PATH, options=options,
                                    service_log_path=ConstTest.TEST_LOG_PATH)

When I remove line cls.browser.quit() my Test working OK. But It doesn't close Chrome Browser. If I add line cls.browser.quit() It will get error:

ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host

I have search for error ConnectionResetError: [WinError 10054] An existing connection was forcibly closed by the remote host many time and add many solution but It's still got that error

When using as per the current implementation the service will be stoped once your script ends as, subprocess.Popen doesn't send signal on __del__, so the attempt is to close the launched process when __del__ is triggered.

def __del__(self):
    # `subprocess.Popen` doesn't send signal on `__del__`;
    # so we attempt to close the launched process when `__del__`
    # is triggered.
    try:
        self.stop()
    except Exception:
        pass
