Same problem here, but this is not a problem in undetected-chromedriver, but in chrome itself, after it has updated to version 129.

I found something about in here: https://issues.chromium.org/issues/367755364#comment2

They said that won't fix (probably not in 129).

Some things you can try:

• Use --window-position= to hide that blank screen instead of using headless.
  options.add_argument("--window-position=-2400,-2400")

• Using group policy, you can downgrade Chrome to version 128 or use Chrome 130 (Beta), both are working.

• Downgrade: https://support.google.com/chrome/a/answer/7125792

• Using group policy: https://support.google.com/chrome/a/answer/6350036?hl=en&ref_topic=9023448&sjid=13249569283913473483-SA#zippy=%2Croll-back-chrome-browser-to-a-previous-version

• You can try to use some CEF client from these versions too and change options.binary_location

        browser_executable_path = './chrome-win64/chrome.exe'

        driver = uc.Chrome(options=options, browser_executable_path=browser_executable_path)

        browser_executable_path = './chrome-win64/chrome.exe'

        driver = uc.Chrome(options=options, browser_executable_path=browser_executable_path)

I tried installing https://googlechromelabs.github.io/chrome-for-testing/#beta

and set headless=True, but it doesn't work and gives an error, but if I set False, everything works successfully.

class Cian:
    def __init__(self):
        self.user_agent = UserAgent().chrome
        self.options_chrome = uc.ChromeOptions()
        self.options_chrome.add_argument(f'user-agent={self.user_agent}')

        self.driver = uc.Chrome(
            browser_executable_path='chrome/chrome-win64/chrome.exe',
            driver_executable_path='chrome/chromedriver-win64/chromedriver.exe',
            headless=True
            )

I noticed that the site uses a defense. When headless=True is enabled it doesn't give the html page but only when False is disabled it gives the result. How can this problem be solved?

this works for me

options.add_argument("--headless=new")
options.add_argument("--window-position=-2400,-2400")

I think this issue may be related with selenium and chrome 129.
Like links below same issues have been uploaded on selenium issues.
