PssaCmdletAnalysisEngine fails with "Errors found while formatting file" and no additional data

[cythrault]

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

Document formatting fails on seemingly random pieces of code. Even if diagnostics enabled, there no meaningful errors aside from the extension logging these:

[Warn  - 2:02:18 PM] Microsoft.PowerShell.EditorServices.Services.Analysis.PssaCmdletAnalysisEngine: Errors found while formatting file:

@andyleejordan there was a new PSScriptAnalyzer release, there may be a regression with that. @cythrault do you have the newer psscriptanalyzer installed separate from the extension?

@JustinGrote Negative:
PS D:\PSWorkspace> Get-InstalledModule PSScriptAnalyzer
Get-Package: No match was found for the specified search criteria and module names 'PSScriptAnalyzer'.

And the only PSScriptAnalyzer module folder I see on that system is v1.21.0 which is under $env:USERPROFILE\.vscode\extensions\ms-vscode.powershell-2024.0.0\modules\PSScriptAnalyzer

@cythrault if you run Invoke-Scriptanalyzer on your script separately does it work fine? As you said it's a 4k+ line module so you may be running into an edge case with ScriptAnalyzer. VSCode is mostly a passthrough to that functionality so the issue would most likely be fixed there if anywhere instead of this repo.

I cannot reproduce without a copy of your module, I'm not seeing any issues ATM.
