Visual Studio 日志文件中的 System.Runtime.InteropServices.COMException

Question

我使用 Visual Studio 2019。当我打开我的解决方案时，有时我会看到此警报：

如果我点击 Open log btn，我可以看到一个带有以下异常的日志：

System.AggregateException: One or more errors occurred. ---> System.Runtime.InteropServices.COMException: Element not found. (Exception from HRESULT: 0x80070490)

===================

所以，实际上，在此之前，这对我来说不是问题。现在我需要安装this plugin。在我看来，这个错误会阻止正确安装。

我去扩展 -> 市场 -> 输入“打字机” - 插件名称。然后我按下载。在此之后，我尝试重新启动 Visual Studio。最后，我看到以下消息：

“Элемент не найден” - 表示：未找到元素。

我按下查看安装日志，再次看到关于 COM 的异常：

那么有什么问题呢？
