每个项目在启动时抛出 ControllerConnectionException

Question

好吧，我不知道从哪里开始，但让我们开始吧。

所以在两周的时间里，我度过了最后一个工作日，在 VS 2019 (16.11.4) 中一切正常。今天我想开始一个项目，我收到以下错误信息：

Unfortunately, a process used by VS has encountered an unrecoverable error.

堆栈跟踪：

Microsoft.ServiceHub.Client.ControllerConnectionException : Controller terminated before accepting connections. Exit code: -1073741674.

   at async Microsoft.CodeAnalysis.Remote.ServiceHubRemoteHostClient.RequestServiceAsync(<Unknown Parameters>)
   at Microsoft.VisualStudio.Telemetry.WindowsErrorReporting.WatsonReport.GetClrWatsonExceptionInfo(Exception exceptionObject)

其次是另一个错误：

There was an error activating the remote language server. Plese select Help > Send Feedback > Report a problem.

当我创建一个新项目时，也会出现这些错误。我可以无错误地启动 VS19 的唯一方法是，当我在弹出窗口中单击“Continue without code”时。

所以我尝试修复或修改VS。当我想修复它时，它失败了。准备修复信息的弹出窗口正在关闭，没有错误消息。

我没有在互联网上找到那么多信息，尤其是错误代码。

此外，我检测到无法安装或卸载 VS19。另外，我无法安装 VS22，因为它在“准备 VS 安装程序”之后再次中止。再次没有错误弹出。

我真的不知道遥测是干什么用的。这会不会因为防火墙/网络问题导致任何问题，导致我无法安装、修复、卸载 VS？

使用 sfc /scannow 我得到以下几行：

2021-12-16 16:25:52, Info                  CSI    00000293 [SR] Cannot repair member file [l:15]'mscorlib.ni.dll' of NetFx4-mscorlib_ni, version 4.0.15805.350, arch amd64, versionScope neutral, pkt {l:8 b:b03f5f7f11d50a3a} in the store, hash mismatch

这与我的一般问题有什么关系吗？

也许（！）一个非常相似的问题，这个人面临着： https://developercommunity.visualstudio.com/t/visual-studio-installer-vs2019-keep-crashing-sudde/711824

所以...（进一步）我尝试过的事情：

• 再次安装 .NET Frameworks
• 尝试了 VS 和 .NET 的修复工具
• 试图修复 VS19，但我不能
• 现在运行 sfc scan
• 运行 chkdsk 扫描
• 几次重新启动，重新启动 VS，...

你最后解决了吗？
