在并行安装 Visual Studio 2022 RC 后，我现在在安装前运行良好的项目中收到以下错误。XAML 页面和代码隐藏中的命名空间似乎匹配。我已确保已安装目标 Windows SDK。关于我还应该检查什么的任何建议？这是一个 UWP 项目。谢谢。

 Windows.UI.Xaml.UnhandledExceptionEventArgs}
        Exception: {"Method not found: 'Boolean System.Threading.CancellationTokenRegistration.TryDeregister()'."}
        Handled: false
        Message: "System.MissingMethodException: Method not found: 'Boolean System.Threading.CancellationTokenRegistration.TryDeregister()'.\r\n   at System.Threading.Tasks.AsyncInfoToTaskBridge`2.Complete(IAsyncInfo asyncInfo, Func`2 getResultsFunction, AsyncStatus asyncStatus)\r\n   at System.Threading.Tasks.AsyncInfoToTaskBridge`2.CompleteFromAsyncOperation(IAsyncOperation`1 asyncInfo, AsyncStatus asyncStatus)"
        Native View: 0x170119f0 <Information not available, no symbols loaded for Windows.UI.Xaml.dll>

此外，现在当我尝试使用 Windows Template Studio 创建一个新项目时，我得到一个“对象引用未设置为对象错误的实例，其中包含以下详细信息：

 System.NullReferenceException: Object reference not set to an instance of an object.
       at Microsoft.Templates.Core.Gen.GenController.ValidateUserSelection(UserSelection userSelection, Boolean isNewProject)
       at Microsoft.Templates.Core.Gen.NewProjectGenController.<UnsafeGenerateProjectAsync>d__4.MoveNext()
    --- End of stack trace from previous location where exception was thrown ---
       at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)
       at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
       at Microsoft.Templates.UI.Services.GenerationService.<GenerateProjectAsync>d__5.MoveNext()

我想这些问题一定是相关的。
