WinForm中Auth0Client.LoginAsync异步死锁及线程模式错误求助

主Windows窗体中已实现Auth0登录功能，认证窗口可正常弹出并成功返回Token，代码如下：

var oidClient = new Auth0Client(options);
LoginResult result = await oidClient.LoginAsync();

当主认证流程获取的Token过期后，尝试在另一个Windows窗体中复用类似逻辑实现Auth0登录时遇到问题：代码陷入无响应状态，疑似异步死锁。尝试了三种方案均未解决：

• 方案1返回“Cannot change thread mode after it is set”错误
• 所有方案均无法弹出Auth0认证窗口

尝试的代码如下：

public LoginResult AuthenticateViaAuth0()
{
    try
    {
        if (SynchronizationContext.Current == null)
        {
            SynchronizationContext.SetSynchronizationContext(new WindowsFormsSynchronizationContext());
        }

        var options = new Auth0ClientOptions
        {
            ClientId = WConstants.AUTH0_CLIENT_ID,
            Domain = WConstants.AUTH0_DOMAIN,
            EnableTelemetry = true,
            RedirectUri = WConstants.AUTH0_REDIRECT_URI
        };
        
        //try 1
        var oidClient = new Auth0Client(options);
        var result = Task.Run(async () => await oidClient.LoginAsync());
        //cannot change threadmode after it is set error
        return result.Result;

        //try 2
        //loginResult = await oidClient.LoginAsync();
        //running nonstop

        //try3
        //Task<LoginResult> rr = oidClient.LoginAsync();
        //var result = rr.ConfigureAwait(false);
        //bool state = true;

        //do
        //{
        //    if (rr.IsCompleted)
        //    {
        //        state = false;
        //        this.loginResult = result.GetAwaiter().GetResult();

        //    }
        //} while (state = true);
        //return this.loginResult;
        //Running not stopping
    }
    catch (Exception ex)
    {
        //exception handling
    }
}

注：同一窗体中曾遇到GraphQL API请求的异步死锁问题，已通过以下代码解决且运行正常：

var graphQLResponse = Task.Run(async () => await graphQLClient.SendQueryAsync<Template>(graphQLRequest)).Result;

提前感谢各位的帮助。
