无法启动Visual Studio 2019的并发可视化器

Question

这与Visual Studio 2012中的Cannot start Concurrency Visualizer非常相似。收到错误"无法启动ETW收集";但误差是不同的。如果我从VS2019启动并发可视化器，它会显示错误"无法启动ETW收集"，但如果我从命令行CVCollectionCmd.exe /Launch exe_path运行它，错误是

A fatal error happened while running the application: Failed to start the "NT Kernel Session"和堆栈跟踪

Exception 'System.ServiceModel.FaultException`1[Microsoft.ConcurrencyVisualizer.Common.CollectionFault]', trace:

如果我启动CVCollectionCmd.exe /Query，它报告Not collecting, ready to start.
