Selenium-manager.exe console window briefly popping up

When you build the script below into an executable using Pyinstaller by running pyinstaller --windowed my_script.py a console window named selenium-manager.exe briefly pops up. This only occurs if you run the executable and not the script as a python file, I'm assuming this cause there's already a console window so windows doesn't create a new one.

I've narrowed it down to the following method selenium.webdriver.common.selenium_manager.SeleniumManager.run. I believe this is caused by the call to subprocess.run which on windows if made without the flagcreationflags=subprocess.CREATE_NO_WINDOW a console window is created if one is unavailable.

Possible fix:

if sys.platform == "win32":
     completed_proc = subprocess.run(args, stdout=subprocess.PIPE, stderr=subprocess.PIPE, creationflags=subprocess.CREATE_NO_WINDOW)
else: 
     completed_proc = subprocess.run(args, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

For the code below run: pyinstaller --windowed my_script.py

from subprocess import CREATE_NO_WINDOW
from selenium.webdriver.chrome.service import Service
from selenium.webdriver import Chrome, ChromeOptions

def setup_options(options: ChromeOptions) -> ChromeOptions :
    options.add_argument('--headless=new')
    options.add_argument('--disable-extensions')
    options.add_argument('--disable-infobars')
    options.add_argument('--no-sandbox')
    return options

def setup_driver() -> Chrome:
    service_chrome = Service()
    service_chrome.creation_flags = CREATE_NO_WINDOW
    options = setup_options(ChromeOptions())
    return Chrome(service=service_chrome, options=options)

driver = setup_driver()
# Do some automation
driver.quit()
