Xamarin.Android中WebAuthenticator Activity实例化异常求助

在Xamarin.Android中使用WebAuthenticator对接巴西政府外部服务登录时，每次都会抛出Java.Lang.RuntimeException: 'Unable to instantiate activity ComponentInfo异常，iOS端运行正常。

实现的WebAuthenticatorCallbackActivity类 #

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);
        }
    }
}

认证器调用代码 #

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);

已尝试更新相关NuGet包、修改Activity名称、在其他分支重建项目等方案，但问题仍未解决。
