JWT授权验证失败：Base64UrlEncoder.Decode方法缺失导致头部无法解码的问题求助

我正在开发API的JWT授权模块，目前遇到了一个棘手的问题——根据抛出的异常栈信息，JWT的头部无法被正常解码。

我收到的具体异常信息如下：

[Authentication failed]
[1º] Method not found: 'Void Microsoft.IdentityModel.Tokens.Base64UrlEncoder.Decode(System.ReadOnlySpan1<Char>, System.Span1)'.
[2º] IDX14102: Unable to decode the header '[PII of type 'Microsoft.IdentityModel.Logging.SecurityArtifact' is hidden. For more details, see https://aka.ms/IdentityModel/PII.]' as Base64Url encoded string.

我已经反复检查过请求的正确性（请求头里确实传递了Authorization: Bearer <token>），也核对了当前使用的NuGet包版本，但始终找不到这个解码方法的替代方案，也不清楚该如何正确修复头部解码的逻辑，希望能得到大家的帮助。

以下是我生成JWT Token的服务代码：

using Microsoft.IdentityModel.Tokens;
using System.IdentityModel.Tokens.Jwt;
using System.Security.Claims;
using System.Text;
using Vestis.Configurations;

namespace Vestis.Services;

public class JwtService
{
    private readonly JwtSettings _jwtSettings;

    public JwtService(JwtSettings jwtSettings)
    {
        _jwtSettings = jwtSettings;
    }

    public string GenerateToken(string userId, string userEmail)
    {
        var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_jwtSettings.SecretKey));
        var credentials = new SigningCredentials(key, SecurityAlgorithms.HmacSha256);

        var claims = new List<Claim>
        {
            new Claim(JwtRegisteredClaimNames.Sub, userId),
            new Claim(JwtRegisteredClaimNames.Email, userEmail),
            new Claim(JwtRegisteredClaimNames.Jti, Guid.NewGuid().ToString())
        };

        var token = new JwtSecurityToken(
            issuer: _jwtSettings.Issuer,
            audience: _jwtSettings.Audience,
            claims: claims,
            expires: DateTime.UtcNow.AddMinutes(_jwtSettings.ExpirationInMinutes),
            signingCredentials: credentials
        );

        var tokenString = new JwtSecurityTokenHandler().WriteToken(token);

        // For debugging purposes
        Console.WriteLine($"Generated JWT Token:\n{tokenString}");

        return tokenString;
    }
}

这是我在Program.cs中配置JWT验证的代码：

void ConfigureJWT()
{
    var jwtSettings = new JwtSettings();
    builder.Configuration.GetSection("JwtSettings").Bind(jwtSettings);
    builder.Services.AddSingleton(jwtSettings);

    var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(jwtSettings.SecretKey));

    builder.Services.AddAuthentication(options =>
    {
        options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
        options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
    }).AddJwtBearer(options =>
    {
        options.TokenValidationParameters = new TokenValidationParameters
        {
            ValidateIssuer = true,
            ValidateAudience = true,
            ValidateLifetime = true,
            ValidateIssuerSigningKey = true,
            ValidIssuer = jwtSettings.Issuer,
            ValidAudience = jwtSettings.Audience,
            IssuerSigningKey = key
        };
        options.Events = new JwtBearerEvents
        {
            OnAuthenticationFailed = context =>
            {
                Console.WriteLine("[Authentication failed]\n" + PrintExceptionStack(context.Exception,out _));
                return Task.CompletedTask;
            },
            OnTokenValidated = context =>
            {
                Console.WriteLine("[Token validated]\n" + context.SecurityToken);
                return Task.CompletedTask;
            }
        };
    });
    builder.Services.AddAuthorization();
}

当前使用的NuGet包版本如下（所有包均为最新可用版本，注意Microsoft.IdentityModel.Tokens比其他Microsoft.AspNetCore相关包低一个大版本，但这是该包的最新稳定版）：

<ItemGroup>
