Chrome crashes after launching [Selenium] [Python]

Question

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.

My script:

    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/")

Python error:

  selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: crashed
  (Driver info: chromedriver=2.27.440174 (e97a722caafc2d3a8b807ee115bfb307f7d2cfd9),platform=Windows NT 10.0.14393 x86_64)

Chromedriver log:

[2.638][INFO]: Launching chrome: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-background-networking --disable-client-side-phishing-detection --disable-default-apps --disable-hang-monitor --disable-infobars --disable-popup-blocking --disable-prompt-on-repost --disable-sync --disable-web-resources --enable-logging --ignore-certificate-errors --load-component-extension="C:\Users\hbur3\AppData\Local\Temp\scoped_dir21208_8173\internal" --log-level=0 --metrics-recording-only --no-first-run --password-store=basic --remote-debugging-port=12638 --safebrowsing-disable-auto-update --start-maximized --test-type=webdriver --use-mock-keychain --user-data-dir="C:\Users\hbur3\AppData\Local\Google\Chrome\User Data"

    [6.750][DEBUG]: DevTools request: http://localhost:12638/json/version
    [6.950][DEBUG]: DevTools request failed
        etc...

I have tried a whole range of solutions, including:

Reinstalling Chromedriver
Creating a new Chrome user profile
Copying the default profile elsewhere
Only running when no other Chrome windows were open

I'm loathed to delete my profile and reinstall Chrome, but this may be my only solution.

I think you'll need to do what you're afraid of... see this answer. you can export and import your profile to save time.

Another thing you can try is to start a RemoteWebDriver instead of ChromeDriver. First run the chromedriver.exe, then connect to it:

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

driver = webdriver.Remote(
command_executor='http://localhost:9515/',
desired_capabilities=DesiredCapabilities.CHROME)

If your problem still reporduces, look for an open issue or perhaps open a new one.
