Based off the answer here I am trying to get Chrome to run headless in my script.
The snippet of code below is inside of a function called login() that logs into our ERP system:
if headless == True:
options = Options()
options.headless = True
#Load webdriver
driver = webdriver.Chrome(options=options, executable_path=r'C:/Users/d.kelly/Desktop/Python/chromedriver_win32/chromedriver.exe')
if headless == False:
driver = webdriver.Chrome('C:/Users/d.kelly/Desktop/Python/chromedriver_win32/chromedriver.exe')
window_before_login = driver.window_handles[0]
### Removed Code Block that fills out login form and clicks 'Login' button ###
# Switch to new window ERP (PLEX) launches and close original blank one no longer needed.
window_before_login = driver.window_handles[0]
window_title = driver.title
driver.switch_to.window(window_before_login)
driver.close()
driver.switch_to.window(driver.window_handles[0])
When I call my function like so:
login(headless=False)
It throws no errors and my entire script executes just fine.
When I call my function like this:
def login(headless=True)
I get the following errors:

I am using Chrome Version 79.0.3945.130 (Official Build) (64-bit), Selenium 3.141.0, and Python 3.7.4.
Any ideas what I am doing wrong? Thank you!
