Since you're running on windows, you'll need to add the --disable-gpu argument when using headless. See https://developers.google.com/web/updates/2017/04/headless-chrome

In selenium version 3.9 which you say you're using, you can also use the convenience method set_headless() which will add both --headless and --disable-gpu for you. In newer versions it's a setter options.headless = True
