C# 模板Xamarin.Forms Shell应用程序中的InvalidCastException

启动模板Xamarin.Forms Shell应用程序时，我在应用程序启动时遇到以下异常：

System.InvalidCastException: Unable to cast object of type 'Mono.Debugger.Soft.PointerValue' to type 'Mono.Debugger.Soft.PrimitiveValue'.

日志的这一段紧跟在与热重新加载相关的几行之前，因此根据提示，我禁用了该功能，并且不会发生异常。所以这肯定是相关的，但这仍然不能告诉我到底发生了什么

我正在运行Xamarin.Forms 5.0.0.2012和Xamarin.Essentials 1.6.1。这在选项卡式模板和弹出式模板中都会发生

据我所知，这不会影响应用程序的功能，热重新加载仍然有效。我很好奇到底发生了什么，如果我能做些什么来修复它？

Visual Studio的版本是什么？尝试更新最新版本，创建新的空白xamarin.shell项目，再次构建。我在那里运行的是v16.9.4，我相信这是截至本文的最新版本？可能还需要注意的是，这是在模拟器中运行的，目标是Android SDK 28。尝试将其他设备作为测试目标，模拟器Android 8.1或真实设备。
