Create WinSCP.SessionOptions takes 20 seconds in COM and account not logged on

Hi,

I use WinSCPnet.dll with a program written with AutoIT script language. It acts as a COM.
It works fine but when I start the program from a scheduled task (under Windows Server 2012 R2) using an user account that is not logged on, it takes 20 seconds for the WinSCP.SessionOptions create object. If I run the scheduled task with a user already logged on, it create the object immediately.

So, I tried with two simple scripts, one with Powershell and one with VBScript.
With Powershell there is no wait time and with VBScript it takes 20 seconds too.

This is the Powershell code:
try
{
    # Load WinSCP .NET assembly
    Add-Type -Path "C:\Program Files (x86)\WinSCP\WinSCPnet.dll"
 
    # Setup session options
    Write-Host $(Get-Date -format "dd/MM/yyyy HH:mm:ss") " Create object WinSCP.SessionOptions`r"
    $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
        Protocol = [WinSCP.Protocol]::Sftp
        HostName = "***.**.***.**"
        UserName = "AldoProva"
        Password = "***"
        SshHostKeyFingerprint = "ssh-rsa 2048 ***"
    }
    Write-Host $(Get-Date -format "dd/MM/yyyy HH:mm:ss") " Object created`r"
 
    Write-Host $(Get-Date -format "dd/MM/yyyy HH:mm:ss") " Create object WinSCP.Session`r"
    $session = New-Object WinSCP.Session
    Write-Host $(Get-Date -format "dd/MM/yyyy HH:mm:ss") " Object created`r"
 
    try
    {
        # Connect
        Write-Host $(Get-Date -format "dd/MM/yyyy HH:mm:ss") " Open Session`r"
        $session.Open($sessionOptions)
        Write-Host $(Get-Date -format "dd/MM/yyyy HH:mm:ss") " Session opened`r"
 
        # Upload files
        Write-Host $(Get-Date -format "dd/MM/yyyy HH:mm:ss") " Create object WinSCP.TransferOptions`r"
        $transferOptions = New-Object WinSCP.TransferOptions
        Write-Host $(Get-Date -format "dd/MM/yyyy HH:mm:ss") " Object created`r"
        $transferOptions.TransferMode = [WinSCP.TransferMode]::Binary
 
        $transferResult =
            $session.PutFiles("E:\test.txt", "/", $False, $transferOptions)
 
        # Throw on any error
        $transferResult.Check()
 
        # Print results
        foreach ($transfer in $transferResult.Transfers)
        {
            Write-Host $(Get-Date -format "dd/MM/yyyy HH:mm:ss") " Upload of $($transfer.FileName) succeeded`r"
        }
    }
    finally
    {
        # Disconnect, clean up
        $session.Dispose()
    }

    Write-Host "`r"
    exit 0
}
catch
{
    Write-Host "Error: $($_.Exception.Message)"
    exit 1
}
This is the result... started with "powershell -file E:\Aldo\testps.ps1 >>E:\Aldo\testps.log" command.

Set transferResult = session.PutFiles("E:\test.txt", "/", False, transferOptions)

Next

Do you have ideas on how to avoid these 20 seconds wait in COM using?
I tried with WinSCP 5.9.4, 5.11.3 and the last 5.13. Always the same result.

Grazie. Ciao,
Aldo

Sorry, I do not know.
But the delay most probably happens even before the assembly is loaded.
