Hangs on ArgumentCompleter Debugging

[JustinGrote]

Example Code:

using namespace System.Management.Automation
$MSIHelper = {
    param($commandName, $parameterName, $wordToComplete, $commandAst, $fakeBoundParameters)

    if ($GLOBAL:ACDebug) {
        $CommandName | Write-Host -fore darkgreen
        $ParameterName | Write-Host -fore darkcyan
        $wordToComplete | Write-Host -fore darkyellow
        $commandAst | ft | Out-String | Write-Host -fore magenta
        $fakeBoundParameters | ft | out-string | write-host -fore green
    }
    [CompletionResult]::new(
        'test', #completionText
        'testListItem', #listItemText
        [CompletionResultType]::ParameterValue, #resultType
        'testToolTip' #toolTip
    )
}
Register-ArgumentCompleter -CommandName New-AzureADServiceAppRoleAssignment -ScriptBlock $MSIHelper

When dotsourcing this from a file and then starting interactive debug with F5, upon attempting the completion it starts debug and stops at the correct line and displays all the info, however the console is hung and none of the debug buttons (run, step into/out/etc) work. Stop does work, but the integrated console totally hangs and requires a restart.

@JustinGrote Do you know if this continues to repro with the latest Preview? @babysnakes What version of the extension are you using?

[babysnakes]

@andschwa , I'm using current latest (2021.12.0).

Thanks

EDIT: forgot to mention, I'm using PowerShell 7.2 on windows 10.

@babysnakes Can you try the latest version of PowerShell Preview for VS Code? Thanks again!

[babysnakes]

@andschwa sure, I'll try tomorrow and update.
