Cant navigate to different directories in sftp server using SSH.NET

I am trying to make code that will navigate throughout my sftp server using SSH.NET library, and I'm having trouble with the navigation. They have a built in way of changing the current working directory with client.ChangeDirectory, and you can access the directory with client.WorkingDirectory. However, this doesn't seem to do anything at all when I use it. Even though I change the workign directory, and I see the string change, when I do "pwd" in ssh to access the current directory, it is always the root no matter what. The second method to navigate would be to just use cd in ssh, using cSSH.RunCommand("cd ..."). However, this has the same issue where it doesn't seem to change the directory at all. Not sure why, but none of these methods work. I've been trying for a long time now but cant seem to figure out why. Thanks.

public async Task GetInformation(string url)

    //Start Connections
    SshClient cSSH = new SshClient(sftpConfig.Host, sftpConfig.Port, sftpConfig.UserName, sftpConfig.Password);
    SftpClient client = new SftpClient(sftpConfig.Host, sftpConfig.Port, sftpConfig.UserName, sftpConfig.Password);

    cSSH.Connect();

    //Clone repo
    SshCommand x = cSSH.RunCommand($"git clone {url}");

    //Close connections
    client.ChangeDirectory("/root");
    cSSH.RunCommand("rm -r di-visualizer");
    client.Disconnect();
    cSSH.Disconnect();
}

and just to be clear, this problem is only happening in my C# code, when i connect using my terminal this does not happen

curious to me this works

using var ff = new SftpClient("192.168.2.50", "root", "...");
ff.Connect();
Console.WriteLine(ff.WorkingDirectory);
ff.ChangeDirectory("/etc");
Console.WriteLine(ff.WorkingDirectory);
ff.Disconnect();

using var ff = new SftpClient("192.168.2.50", "root", "...");
ff.Connect();
Console.WriteLine(ff.WorkingDirectory);
ff.ChangeDirectory("/etc");
Console.WriteLine(ff.WorkingDirectory);
ff.Disconnect();

maybe you can compare with another tool, even if only using plink/sftp by Process.Start

i can change the working directory just fine, cause in the yellow i am not at root anymore. but the problem is that when i do dotnet run -r roslyn, it says there is no csproj in the directory
