gRPC IFeatureCollection已被释放。对象名：'Collection‘

使用c# gRPC服务器时，我让IServerStreamWriter<ClientNotification> ClientNotificationStream发送用户通知
当我试着给ClientNotificationStream.WriteAsync(parameters)打电话的时候
System.ObjectDisposedException: 'IFeatureCollection has been disposed.
Object name: 'Collection'.'```
IFeatureCollection has been disposed.

我补充说，当我需要执行WriteAsync().To修复它时，ClientNotificationStream已被释放
WaitHandle.WaitAny(new[] { context.CancellationToken.WaitHandle });
context为ServerCallContext
