[🐛 Bug]: headless mode error of chrome 129

[magdev2022]

What happened?

Today, I updated the Chrome browser to the latest version (129).
After the update, running Chrome in headless mode produces an unusual result: a blank white window appears, matching the size of the browser.

How can we reproduce the issue?

//simple code
var driverService = ChromeDriverService.CreateDefaultService();
driverService.HideCommandPromptWindow = true;
var chromeoptions = new ChromeOptions();
chromeoptions.AddArgument("headless");
var botdriver= new ChromeDriver(driverService, chromeoptions);
botdriver.Url = "https://google.com";

Relevant log output

I will send later.

Temporary fix to move the window off-screen:
--window-position=-2400,-2400

chrome_options.add_argument("--window-position=-2400,-2400")
