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.
