C# SELENIUM: Can't access URL after setting custom FIREFOX profile

Question

I am trying to connect to profile, its successfully connect to custom firefox profile, but the problem after that is command FirefoxDriver driver = new FirefoxDriver(options); no more works, works only if i remove options then no custom profile.

the before last line returns error OpenQA.Selenium.WebDriverException: 'Process unexpectedly closed with status 0' or The HTTP request to the remote WebDriver timed out after 60 seconds, it only works if I remove options inside FirefoxDriver: FirefoxDriver driver = new FirefoxDriver(options);

Also, doing options.AddArgument("-profile" + "C:\Users\Chill\AppData\Roaming\Mozilla\Firefox\Profiles\5k2mdm2k.myprofile"); instead of spliting the 2 arguments does not launch firefox in the right profile.

Or even options.AddArgument("no-sandbox") or options.AddArgument("-no-sandbox") or options.AddArgument("--no-sandbox") doesn't works, also --profile instead of -profile does not open the right profile also, here is my code anyway:

using System;
using OpenQA.Selenium;                  // nuget package name: Selenium.WebDriver
using OpenQA.Selenium.Firefox;          // nuget package name: Selenium.WebDriver.GeckoDriver

namespace ConsoleApp2
{
    class Program
    {
        static void Main(string[] args)
        {
            FirefoxOptions options = new FirefoxOptions();
            options.AddArgument("-profile");
            options.AddArgument(@"C:\Users\Chill\AppData\Roaming\Mozilla\Firefox\Profiles\5k2mdm2k.myprofile");    /* type about:profiles in firefox bar to create and manage firefox profiles, from there you will see which profile used, make sure to not use the default one and use root directory */
            FirefoxDriver driver = new FirefoxDriver(options);    /* code stops here and puts error after closing browser or waiting until it close itself after 60 sec */
            driver.Navigate().GoToUrl("https://www.google.com/");    /* can only reach this part of code if i remove turn FirefoxDriver(options); to FirefoxDriver(); on the line upper, but no more custom profile so */
        }
    }
}

Hope you can help im blocked on this step for 3 days

Using these nugget versions:

 <PackageReference Include="Selenium.Firefox.WebDriver" Version="0.27.0" />
 <PackageReference Include="Selenium.WebDriver" Version="4.0.0-beta4" />

This works for me:

using OpenQA.Selenium.Firefox;
using System;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            var options = new FirefoxOptions();
            var profile = new FirefoxProfile(@"C:\Users\CatalinR\AppData\Roaming\Mozilla\Firefox\Profiles\f9n067l1.default");

            options.Profile = profile;
            var driver = new FirefoxDriver(options);  
            driver.Navigate().GoToUrl("https://www.google.com/");   
        }
    }
}
