这是一个非常奇怪的问题。我试图为我遇到的Xamarin问题创建一个示例项目。我为Android、iOS和UWP创建了一个"空白"的Xamarin项目，但没有做任何更改。我在调试模式下运行了它，然后崩溃了。调试输出为

切换到"释放"模式，应用程序就会运行。现在奇怪的是，我已经尝试了4次，每次都以相同的方式出现，在调试模式下崩溃。
我的机器上似乎有"通用"的东西损坏了。我需要清理什么才能使调试模式重新工作。
B.t.w.我正在开发的应用程序(这只是一个证明Xamarin中错误的项目(运行良好，我可以在调试模式下运行它。
问题是Visual Studio中名为"使用快速部署(仅限调试模式("的设置。如果我关闭了调试功能，请在我的手机上重新开始工作。
