[🐛 Bug]: Unable to add cookies in Selenium v4.26.0

[jeron-kleinfehn-surescripts]

What happened?

After creating a driver instance, we are unable to add cookies to the driver. Here is a .Net console app that repoduces the issue:

Reference nuget package: PackageReference Include="Selenium.WebDriver" Version="4.26.0"

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

namespace SeleniumCookies
{
    internal class Program
    {
        static void Main(string[] args)
        {

            List<Cookie> cookies = new List<Cookie>();
            using (IWebDriver driver = new ChromeDriver())
            {
                // Navigate to a webpage
                driver.Navigate().GoToUrl("https://www.google.com");

                cookies = driver.Manage().Cookies.AllCookies.ToList();

                foreach (var cookie in cookies)
                {
                    driver.Manage().Cookies.AddCookie(cookie);
                }

                // Close the browser
                driver.Quit();
            }
        }
    }
}

Note: This only started happening in the Selenium 4.26.0 release. This works fine in the Selenium 4.25.0 release.

How can we reproduce the issue?

You can reproduce the issue by trying to add a cookie to a driver.  See the 'What happened' section for a code snippet.
