ILRuntime在热更代码中的Task异步报错无法定位到具体热更什么代码中，可以在抛出该异常前先捕获到热更的堆栈(ILIntepreter.cs:151)：

                var thisObj = RetriveObject(arg, mStack);

                if (thisObj == null){

                    var err = this.AppDomain.DebugService.GetStackTrace(this);

                    throw new NullReferenceException(err);

                }
