[Python] Shadow Root only found on Windows and not on Mac?

i have the following code where i want to access a shadow root using selenium: This is working fine when i run this code on my windows computer.

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
import time

print(f"Checking Browser driver...")
options = Options()
options.add_argument("start-maximized")
options.add_argument('--log-level=3')
options.add_experimental_option("prefs", {"profile.default_content_setting_values.notifications": 1})
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('excludeSwitches', ['enable-logging'])
options.add_experimental_option('useAutomationExtension', False)
options.add_argument('--disable-blink-features=AutomationControlled')
srv=Service()
driver = webdriver.Chrome (service=srv, options=options)
waitWD = WebDriverWait (driver, 10)

link = "https://www.firmy.cz/kraj-liberecky/liberec/1818-liberec?q="
driver.get (link)
time.sleep(5)
shadowHost = driver.find_element(By.XPATH,'//div[@class="szn-cmp-dialog-container"]')
shadowRoot = shadowHost.shadow_root
time.sleep(5)
shadowRoot.find_element(By.CSS_SELECTOR, 'button[data-testid="cw-button-agree-with-ads"]').click()
input("Finished!")


But when i try to run this on my Mac-computer i get this error message:
