I keep getting the same error with selenium trying to control chrome.

This is my code and the error that I get. I already opened chromedriver and allowed it to be executed from the security in pref system.

from selenium import webdriver
from selenium.webdriver.chrome. options import Options
from selenium. webdriver. chrome. service import Service


s= Service('chromedriver')
chromeOptions = Options ()
driver = webdriver. Chrome (service=s, options=chromeOptions)

WebDriverException                        Traceback (most recent call last)

We're using python's selenium's webdriver-manager to manage our driver and had this same error from this line

driver = webdriver.Chrome(ChromeDriverManager().install())

To fix it, we opened a chrome window -> settings -> about chrome -> update chrome. Or chrome://settings/help on your browser.

After it finished building the new version of chrome, that same line no longer generates the error.

Of course, this only worked since Google had pushed a new version of chrome with a bugfix for whatever was causing that.
