title: Chrome crashes after launching [Selenium] [Python]
body: <p>I have written a small script to load my default Chrome profile and open a site using Selenium. However, after chrome successfully launches, the code pauses for a while and then crashes. </p>
  
  <p><strong>My script:</strong></p>
  
  <pre><code>    options = webdriver.ChromeOptions() 
      options.add_argument("--user-data-dir=C:\\Users\\hbur3\\AppData\\Local\\Google\\Chrome\\User Data") 
      options.add_argument("--start-maximized");
      wd = webdriver.Chrome(chrome_options=options)
      wd.get("https://google.com.au/")
  </code></pre>
  
  <p><strong>Python error:</strong></p>
  
  <pre><code>  selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: crashed

  <p>I have tried a whole range of solutions, including:</p>
  
  <ul>
  <li>Reinstalling Chromedriver</li>
  <li>Creating a new Chrome user profile</li>
  <li>Copying the default profile elsewhere</li>
  <li>Only running when no other Chrome windows were open</li>
  </ul>
  
  <p>I'm loathed to delete my profile and reinstall Chrome, but this may be my only solution. </p>
