[英]VS2017 crashes with 'FileNotFoundEx: System.Runtime.CompilerServices.Unsafe, V=4.0.4.1' upon loading any project
很抱歉我寫了一篇冗長的文章，但我正處於困境中 - 只是想預先提供所有詳細信息。
這個星期五（2021 年 11 月 12 日）在重新啟動 Visual Studio 2017 后，在打開現有解決方案時開始在沒有通知的情況下崩潰。 這至少在一周前運行良好（在 2021 年 11 月 5 日上次 Win10 更新 KB5006670 之后 - 然后重新啟動）。 嘗試加載舊解決方案（2 年多沒有接觸過）會導致完全相同的行為：
你瞥見了“加載項目..”窗口（不確定它是否通過解決方案中的所有項目），然后突然主VS窗口消失了......就是這樣。
VStudio 的配置至少有一年沒有碰過。 也沒有明確的更新/補丁或 NuGet 包。 VS 本身會啟動並顯示帶有通常開始頁面的主窗口。 但我無法加載任何解決方案或項目。

Roslyn.Utilities.TaskExtensions.ReportFatalErrorWorker()似乎是一個常見的故障捕捉器，所以我猜這個問題與后台代碼分析有關，在加載解決方案時啟動。 誰打破了它以及如何？

但這些都沒有描述我的場景。 在我的任何項目中，我都沒有對該庫的任何 [已知] 依賴。 直到星期五我什至不知道它！
在嘗試可能的補救措施之前，在3接受的答案中建議（“在我為該 DLL 運行 NuGet 更新后錯誤消失了”），我想了解到底發生了什么（以及如何發生！）？ 我的列表中沒有此類 NuGet 包的顯式條目。 我最近沒有安裝或更改任何東西。
這場慘敗正是我嘗試保持很少變化的 [=> known & stable] 開發環境的原因。

抱歉拖了這么久。 在槍下完成一個項目..
問題的根源竟然是ICSharpCode.CodeConverter ！
哇，在所有安裝的部件中（不是那么多）。
憑直覺，我開始尋找 Visual Studio 的工具和擴展，並注意到此組件上的安裝日期是幾天前。 我沒有明確更新它！ 啊，是的，這里是自動更新此擴展復選框，它當然被選中（默認情況下）。
問題是，大多數擴展不允許我關閉自動更新。 嘿，@JialeXue 那是怎么回事？！
至少你應該告訴我們環境在我們不知情的情況下發生了變化！
這是C:\\TEMP\\VSIXInstaller_f0335270-1a19-4b71-b74b-e50511bcd107.log ：

一旦我刪除了這個組件，VStudio 就開始正常運行了！ 不需要重新啟動。 在它甚至會崩潰之前初始化/打開一個新的空項目！
在閱讀有關此轉換器的文檔時，我還發現了一個非常相似的錯誤。
這是目前的對話框。 請注意禁用自動更新復選框和安裝日期- 上次我在那里是 11 月 15 日！ 11 月 20 日發生了什么？ 我怎么知道？
當然，我們需要不時更新我們的系統。 但是（我在看着你，微軟）：
