Xamarin.ios Xamarin iOS&；Mac-编译器崩溃，代码为：1

突然，我所有的Xamarin项目都停止了构建，出现了上面提到的编译错误。我还试着为Mac重新安装XS和VS，但没有任何帮助

这是我得到的构建输出：

CustomDialogController.designer.cs(16,22): warning CS0114: 'CustomDialogController.Description' hides inherited member 'NSObject.Description'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.
CustomDialogController.designer.cs(19,22): warning CS0114: 'CustomDialogController.Title' hides inherited member 'NSViewController.Title'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.
