你也可以启动Visual Studio安装程序。安装程序似乎可以修复任何背景问题。然后，您可以从安装程序启动Visual Studio。

我刚才用这种方法解决了我的问题。

原因是一个待定的Windows更新。Windows更新后，Visual Studio启动没有任何问题。

我在任务管理器上发现，当我试图启动VS2017的生产版本时，VS预览2019版本正在更新。以前从来没有这个问题。就像其他人建议的那样，我等了大约3分钟，问题平息了下来，没有产生重大影响。这种方式比通过任务管理器处理任务要好得多。: -)

很可能Visual Studio正在更新，就像错误消息暗示的那样，如果你等待几分钟更新完成，你应该能够再次运行Visual Studio而没有问题。

If the problem persists or if you're just curious, open up your task manager and see if there is anything related to (Microsoft) Visual Studio running but don't just kill the process. Check instead if the process is using any resources - if it has a high I/O count, then it's actually updating and you should let it do its thing. If CPU-usage and memory usage remain mostly constant and there is no disk activity for the process for several minutes, this could mean that the process is stuck. You might have to kill it, but proceed with caution. Hopefully if this is an update for Visual Studio, the process name should include a version number or some sort of indication of what kind of update is being applied that you can use to search for more information through a search engine or through Microsoft's online resources.

启动任务管理器并关闭Windows安装程序。

解决方案:不要只是打开任务管理器并杀死vsautoupdate .exe正在更新的所有进程，这将在您尝试启动Visual Studio时出现问题，因为更新未完成。相反，等待更新完成，这是当你启动Visual Studio。如果你不再需要定期更新的Visual Studio组件，同样建议通过Visual Studio安装程序卸载该组件
