Getting "Registration response error messages" with Chromedriver 138.0.7204.92 in selenium

[And Gra]

I suddenly get a lot of error messages in Chromedriver 138, which wasn't the case up to and including the version 137, when using it with selenium. Even a very simple code will produce these error messages.

Example code:

print("Starting...")
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.chrome.options import Options
import time

chrome_options = Options()
chrome_options.add_argument("--disable-search-engine-choice-screen")
driver = webdriver.Chrome(options=chrome_options)
driver.maximize_window()
driver.get('https://stackoverflow.com')

time.sleep(5)
driver.close()
driver.quit()

Output:

Starting...

I'm not even using selenium on a phone but on a desktop PC and the script doesn't have anyhting to do with GCM or mobile communication so I wonder why these messages appear.

I'm seeing the same issue, but only observing it when the -headless flag is added.
