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 PowerShell Editor Services itself and does not reproduce in a standalone PowerShell instance, and is not an issue with my editor.
• I have verified that I am using the latest version of PowerShell Editor Services.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

When the following code snippet is encountered in a user created PowerShell script, and the script's path is in the environment path variable, PowerShellEditorServices fails. This appears to be caused by a Newtonsoft.Json.JsonSerializationException (For additional details, see the included PowerShellEditorServices-14896.log file included below).

Because the PowerShellEditorServices is used by the PowerShell Extension for Visual Studio Code, both the extension's Command Explorer and Intellisense stop working when this exception occurs. Ideally, I feel the PowerShellEditorServices should gracefully handle and report the exception and continue running.

Steps to Reproduce

In Windows 11:

1. Insert aforementioned code snippet into any user defined PowerShell script.
2. Make sure the script can be found by the PowerShellEditorServices by including its fully qualified path (not file name) in the path environment variable.
3. Open Visual Studio Code (with the PowerShell for VS Code extension (by Microsoft) installed.
4. Click on the PowerShell icon in the left panel, to show the Command Explorer. (You may need to enable this extension's setting: PowerShell>SideBar: Command Explorer Visibility
5. The Command Explorer will fail to enumerate and Intellisense will stop working for PowerShell scripts.
