How can I invoke multiple Robocopy.exe commands AsJobs?

Question

Don't beat me up to much guys, I was trying to understand the other similair questions asked about this issue, just wasn't able to decipher them.

I'm using the below code snipet to copy folders, seperately, on a "remote" computer using Start-Job:

$Folders = @('Desktop','Documents','Favorites','Links','Downloads','Music','Videos','Pictures','Contacts') 
    
    Foreach($Folder in $Folders){
        $ArgumentsArray  = @()
        $ArgumentsArray += "\\$Env:COMPUTERNAME\c$\Users\Abraham\$Folder"
        $ArgumentsArray += "C:\CopyBackup"
        $RoboCopy_Args   =  @("/E","/R:5","/W:1","/MT:13")
    
        Start-Job -ScriptBlock { & C:\Windows\System32\Robocopy.exe $args[0] "$($args[1])\$using:Folder" $using:RoboCopy_Args } -ArgumentList $ArgumentsArray -Name $Folder
    }

The code works as intended.

Now, the issue is when I try to invoke the command remotely using Invoke-Command -AsJob. Error reads:

The pipeline was not run because a pipeline is already running. Pipelines cannot be run concurrently.

Which I tried to read and understand before coming here but, wasn't able to understand why it won't work. What's odd, is that the first folder in the $Folders array (Desktop) does get copied as a job, shows completed, but the other show failed immediately. So I ran Receive-Job -Name Documents and is where I got the above error.

• What does this have to do with the pipeline?
• Is there a work around solution?

Failed Code:

$PSSession = New-PSSession -ComputerName $env:COMPUTERNAME -ErrorAction Stop

$Folders = @('Desktop','Documents','Favorites','Links','Downloads','Music','Videos','Pictures','Contacts') 
    
    Foreach($Folder in $Folders){
        $ArgumentsArray  = @()
        $ArgumentsArray += "C:\Users\Abraham\$Folder"
        $ArgumentsArray += "C:\CopyBackup"
        $RoboCopy_Args   =  @("/E","/R:5","/W:1","/MT:13")
    
        Invoke-Command -ScriptBlock { & C:\Windows\System32\Robocopy.exe $args[0] "$($args[1])\$using:Folder" $using:RoboCopy_Args } -AsJob -ArgumentList $ArgumentsArray -Session $PSSession -JobName $Folder
    }

I'd like to stick with running this "as jobs" due to the event produced by it, StateChanged, which im using for a different purpose.

EDIT: I've decided to wrap it all into one single Invoke-Command and send it over, but it's still copying one at a time.

$PSSession = New-PSSession -ComputerName $env:COMPUTERNAME -ErrorAction Stop

    
Invoke-Command -ScriptBlock {

    $Folders = @('Desktop','Documents','Favorites','Links','Downloads','Music','Videos','Pictures','Contacts') 
        foreach ($Folder in $Folders) {



            $ArgumentsArray  = @()
            $ArgumentsArray += "C:\Users\Abraham\$Folder"
            $ArgumentsArray += "C:\CopyBackup"
            $RoboCopy_Args   =  @("/E","/R:5","/W:1","/MT:13")
        
            Start-job {

                & C:\Windows\System32\Robocopy.exe $args[0] "$($args[1])\$using:Folder" $using:RoboCopy_Args
            
            } -ArgumentList $ArgumentsArray -Name $Folder
        } 
} -AsJob -Session $PSSession -JobName $Folder
