"Run selection" does nothing

Issue Type: Bug

I have an open Workspace in Visual Code and select a specific PowerShell Script. Then I select the function incl. “get-teamviewerdevices” to run the function. Right click and select “Run selection” or hitting F8 to test the function does nothing.

My next step was to close the Workspace and open the same PowerShell Script on the same place with a right click “Open in Code” and try again. Now it works as expected?! Any ideas or suggestions?

[string]$accessToken = "<token>"
[string]$tvApiVersion = '<apiversion>'
[string]$tvApiBaseUrl = '<URL>'


function Get-TeamViewerDevices {

    [CmdletBinding(DefaultParameterSetName = "Policy", SupportsShouldProcess = $true)]
    param(
    
        [Parameter(ParameterSetName = 'Policy', Mandatory = $false)]
        [ValidateSet('None', 'Inherit')]
        [string] $Policy = 'Inherit',

        [Parameter(ParameterSetName = 'SpecificPolicy', Mandatory = $true)]
        [string] $PolicyId

    )
    function ConvertTo-TeamViewerRestError {
        param([parameter(ValueFromPipeline)]$err)
        try { return ($err | Out-String | ConvertFrom-Json) }
        catch { return $err }
    }

    function Invoke-TeamViewerRestMethod {
        # Using `Invoke-WebRequest` instead of `Invoke-RestMethod`:
        # There is a known issue for PUT and DELETE operations to hang on Windows Server 2012.

@pilgi3 the preview has a complete rewrite of the core pipelining engine to help make things faster and more stable. The core of it is stable but there may be many new edge cases here and there we are working to smooth over as a result of such a huge change.

Can you provide some more specifics? Run Selection (F8) works just fine for me on selecting a line in a script and having it run in the PSIC at the bottom. (On my computer I have it bound to alt-enter but it’s the same process)

Yes the log files are from an affected device. I will do again and provide the payload logs as well!
