C# ASP.Net核心UWP信号器客户端HubConnectionBuilder.Build崩溃

因此，我们遇到了一个无法解决的错误。 我们使用signar（Core）让服务器向连接的客户端发送数据。施维雅是一个具有.Net核心3.1的API，客户端是UWP客户端。 在调试模式下，一切正常，但当我们创建客户端版本时，信号器连接失败

以下是连接的代码：

var connectUrl = await ControllerManager.Instance.GetAsync<string>($"Signalr/connectionurl");
var token = ControllerManager.Instance.EchinoBearerToken;

 _chatHubConnection = new HubConnectionBuilder()
        .WithUrl($"{connectUrl}/signalr/chathub", options => {
            options.AccessTokenProvider = () => Task.FromResult(token);
        })
        .Build();

下面是失败的堆栈跟踪：
