options.add_argument('start-maximized')
options.add_argument("--headless")
options.add_argument("user-data-dir=C:\\Users\\sd\\AppData\\Local\\Google\\Chrome\\User Data\\Profile 1\\Default")

Might be loading the page too fast. Try looking into this.

Just like Nyan said, you need to wait for the page to load either with a delay (dirty) or you should wait for the specific element you want:
PHP Code
<?php
wait = WebDriverWait(driver, 10)
element = wait.until(element_condition)
The "element_condition" can be the element itself that you're looking for once it appears on the page, or you can use an "expected condition" from the "selenium.webdriver.support.expected_conditions". There are several you can use. I use this for a LinkedIn scraper, just as an example, and it works great.
