JEA Calling Scheduled Task in a Script now fails

Hi,

It looks like one of the security patches has knocked out JEA from running an allowed script unconstrained by a constrained user.

I'm getting back the following error:

An error has occurred while loading script module MSFT_ScheduledTask_v1.0 because it has a different language mode 
than the module manifest. The manifest language mode is ConstrainedLanguage and the module language mode is 
FullLanguage. Ensure all module files are signed or otherwise part of your application allow list configuration.+ CategoryInfo          : InvalidOperation: (:) [Import-Module], PSInvalidOperationException+ FullyQualifiedErrorId : Modules_MismatchedLanguageModes,Microsoft.PowerShell.Commands.ImportModuleCommand 

This was working until I believe Microsoft security updates were applied to the systems.  Using a Jump Server for support personnel to log onto and trigger scripts to run remotely to pull in log files.  Have to use a Scheduled Task to transfer files across the network as the computer account as cannot use a gMSA as the domain is still at 2008 level.

Calling command:

$session = New-PSSession -ComputerName $($ComboBox01.SelectedItem.ToString()) @options
Invoke-Command -Session $session -ScriptBlock {C:\Scripts\FileCopy.ps1 $using:files}
Remove-PSSession $session 

Script File:

# Copy selected files to remote server

[CmdletBinding()]
Param(
    [Parameter(Mandatory=$True,Position=1)]
    [string[]]$FileS
    )

Function Get-Mytime
{
$TimeStamp = Get-Date -Format 'yyyyMMddHHmmss'
"$TimeStamp"
}

#Main Script

    $STUser= "NT AUTHORITY\SYSTEM"
    $STAction = ScheduledTasks\New-ScheduledTaskAction -Execute powershell.exe -Argument "-File c:\scripts\FileTransfer.ps1"
    $STPastTime = New-TimeSpan -Days 10
    $STResTime = (Get-Date) - $STPastTime
    $STTrigger = ScheduledTasks\New-ScheduledTaskTrigger -Once -At $STResTime 
    $STInfo = ScheduledTasks\Register-ScheduledTask -Action $STAction -Trigger $STTrigger -TaskName $STName -Description "File Copy of $STName" -User $STUser
    Write-Host $STInfo
    ScheduledTasks\Start-ScheduledTask -InputObject $STInfo

    While ((Get-ScheduledTask -TaskName $STInfo.TaskName).State  -ne 'Ready')
    {
    Write-Verbose -Message "Waiting on scheduled task..."
    }
    $TSResult = Get-ScheduledTaskInfo -TaskName $STName
    Write-Host "Scheduled Task results"
    Write-Host "Task Result:" $TSResult|Format-List
    #Remove Scheduled Task
    ScheduledTasks\Unregister-ScheduledTask -InputObject $STInfo -Confirm:$false
    del $TempLoc\$ZipName
    del $ConfigFile
    Write-Host "File Transfer Completed"

Any Ideas?
