Xamarin如何跟踪TargetParameterCountException:参数数

因此，我正在构建一个Xamarin Forms应用程序，我想知道如何跟踪导致此异常的原因：

TargetParameterCountException:指定的参数数量与预期数量不匹配

堆栈跟踪没有指向我们的任何代码（堆栈跟踪仅表示异常是从

UIApplication.Main

引发的）

我只是不知道如何跟踪这个异常的来源——如果我逐行检查调试跟踪显示正在运行的代码，那么代码就可以正常工作

这个问题只在应用程序安装后第一次使用时才出现，这给了我一个线索，但我真的不知道在哪里可以进一步调查

编辑：

根据要求，以下是堆栈跟踪：
