`connect ENOENT \\.\pipe\PSES_fskvz4fs.gy4` appears, until VSC has been reinvoked, when a `.PS1` file is invoked in VSC, after cancelling a shutdown that was caused by a PS1 file, which was invoked by VSC.

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

As was originally reported at microsoft/vscode/issues/244192:

connect ENOENT \\.\pipe\PSES_fskvz4fs.gy4 appears when a .PS1 file is invoked in VSC, after cancelling a shutdown that was caused by a PS1 file, which was invoked by VSC. The error ceases to appear after VSC has been (closed, then) reinvoked.

PowerShell Version

I did not collect this at the time. However, if relevant to issues/4332, it may contain them.

Visual Studio Code Version

Version: 1.98.2 (user setup)
Commit: ddc367ed5c8936efe395cffeec279b04ffd7db78
Date: 2025-03-12T13:32:45.399Z
Electron: 34.2.0
ElectronBuildId: 11161602
Chromium: 132.0.6834.196
Node.js: 20.18.2
V8: 13.2.152.36-electron.0
OS: Windows_NT x64 10.0.26120

Steps to Reproduce

1. Invoke a .PS1 file containing shutdown /r /fw via VSC's GUI: ^1

   #!/usr/bin/env pwsh
   #Requires -PSEdition 'Core'
   #Requires -Version 7.5.0
   If ([OperatingSystem]::IsWindows() -Eq $True) {
   	sudo shutdown /r /fw /t 0
   }
   

2. Cancel when it prompts the user to, because of unkillable processes.

3. Reinvoke the file. It causes the undermentioned:

   

4. WM_CLOSE code. ^3

5. Invoke code.

6. Invoke the file again. It'll function.

まず、issue に記載された Windows VS Code の手順を再現します。.PS1 ファイルを呼び出し、シャットダウンをキャンセルし、再度呼び出し、WM_CLOSE で VS Code を閉じてから、再び開きます。拡張機能で利用可能なログと、失敗の前後におけるプロセスまたはパイプの処理を調査します。シャットダウンをキャンセルした後、connect ENOENT エラーなしでファイルを再度呼び出せれば完了です。
