Xamarin Android WebAuthenticator bug - xamarin

Question

Im having a problem using WebAuthenticator on Xamarin.Android
Everytime i try to log in via a external service (Goverment From Brazil) it returns me Java.Lang.RuntimeException: 'Unable to instantiate activity ComponentInfo
Heres the class that implements the WebAuthenticatorCallbackActivity:
using Android.App;
using Android.Content;
using Android.Content.PM;
using Android.OS;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace TesouroDiretoMobile.Configuration.Droid
{
[Activity(NoHistory = true, LaunchMode = LaunchMode.SingleTop, Exported = true, Name = "br.gov.fazenda.tesouro.td.CallBackActivity", Label = "TesouroDireto")]
[IntentFilter(new[] { Android.Content.Intent.ActionView },
Categories = new[] { Android.Content.Intent.CategoryDefault, Android.Content.Intent.CategoryBrowsable },
DataScheme = "tesourodireto://retornologinunico")]
public class AutenticadorGovBr : Xamarin.Essentials.WebAuthenticatorCallbackActivity
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
}
}
}
My android Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:installLocation="auto" package="br.gov.fazenda.tesouro.td" android:versionName="2.3.13" android:versionCode="10826">

</activity>
</application>
</manifest>
The call for the authenticator
var uriBuilder = new StringBuilder(AppSettings.SegurancaBaseAddress);
uriBuilder.Append("/authorize");
uriBuilder.Append($"?response_type={AppSettings.ResponseType}");
uriBuilder.Append($"&client_id={Criptografia.Descriptografar(AppSettings.ClientId)}");
uriBuilder.Append($"&scope={AppSettings.Scope}");
uriBuilder.Append($"&redirect_uri={HttpUtility.UrlEncode(AppSettings.RedirectUri,Encoding.UTF8)}");
uriBuilder.Append($"&nonce={Guid.NewGuid()}");
uriBuilder.Append($"&state={Guid.NewGuid()}");
var authResult = await Xamarin.Essentials.WebAuthenticator.AuthenticateAsync(
new Uri(uriBuilder.ToString()),
new Uri(AppSettings.RedirectUri));
var accessToken = authResult?.Properties["code"];
await IniciarSessaoGovBr(accessToken, string.Empty);
It only happens in android, IOS it works fine
I already tryed updating the packages, changing the name, recreating it all on other branch, and the error keeps ocurring
