Unable to clear the initialization process itself

[jeeth_unity]

Due to
using Unity.Services.Authentication; throwing an error Vivox Service itself cannot be initialized. I have attached 2 screenshots of the Services settings and Vivox settings. What has caused the authentication services to fail. I am unclear

using System;
using UnityEngine;
using Unity.Services.Authentication; //Throws an error
using Unity.Services.Core;
using Unity.Services.Vivox;
using VivoxUnity;

public ILoginSession LoginSession;

async void Start()
{
    await UnityServices.InitializeAsync();
    await AuthenticationService.Instance.SignInAnonymouslyAsync(); //Throws an error

    VivoxService.Instance.Initialize();
}

Any help is appreciated

I have also looked into the authentication beta services but when clicking on to download SDK it takes me to the page shown in the images
