Visual Studio 2015与UWP debbuger和Designer的问题

Question

我是Universal Windows平台的新手，看起来我已经弄乱了一些东西，可能是App.g.i.cs文件。设计师没有这样做：

System.Runtime.InteropServices.COMException
The app didn't start. (Exception from HRESULT: 0x8027025B)

在x86 localMachine上进行调试会抛出类似这样的东西，在ARM设备（我的手机）上调试工作正常。

有什么想法吗？已经尝试过使用UWP Tools重新安装VS并修复VS.
