SessionNotCreatedException: This version of ChromeDriver only supports Chrome version 84 using ChromeDriver and Chrome through Selenium and Python

Your ChromeDriver version and your installed version of Chrome need to match up. You are using ChromeDriver for Chrome version 84, which at the time of this answer, is a beta (non-stable) build of Chrome; you’re probably not using it. Likely you’re on version 83.

Check your Chrome version (Help -> About) and then find the correct ChromeDriver release. You could instead use webdriver-manager which can handle this for you.
