PowerShell 7 APPCRASH System.ArgumentOutOfRangeException

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.
• Refer to the FAQ.
• Refer to Differences between Windows PowerShell 5.1 and PowerShell.

Steps to reproduce

We are experiencing a problem that PowerShell 7.4.0 crashes when using Set-SFTPItem in parallel running jobs. We also reported this in issue 556 of the Open-SSH module.

Looking in the Windows Event Viewer we see 3 errors which happen at exactly the same time. This makes us believe it's the PowerShell process that crashes within the PowerShell background job started by Start-Job.

Possibly related to .NET version 8, see this issue with a similar error message.

See attachment for the event logs.

Repro

Install-Module Posh-ssh

# Main script "Get or send SFTP file.ps1"
$actions | foreach-Object {
   $invokeParams = @{
           FilePath     = '../Send to SFTP.ps1'
           ArgumentList = ....
   }
   Start-Job @invokeParams
}

# Child script "Send to SFTP.ps1"
$ErrorActionPreference = 'Stop'

$params = @{
    ComputerName = $SftpComputerName
    Credential   = $sftpCredential
    AcceptKey    = $true
}
$sftpSession = New-SFTPSession @params

$sessionParams = @{
    SessionId = $sftpSession.SessionID
}
try {
   $params = @{
        Path        = $tempFile.UploadFilePath
        Destination = $SftpPath
   }
   Write-Verbose 'Upload file'
   Set-SFTPItem @sessionParams @params
   Write-Verbose 'File uploaded'
}
catch {
   throw "Failed to upload file: $_"
}

Expected behavior

One of two things:
- See the verbose message "File uploaded"
- See the error message "Failed to upload file: reason"

Actual behavior

When enabling `Start-Transcript` we can see:
> VERBOSE: Upload file

Nothing else after this line. It didn't go to the `catch` clause and no upload has happened. The PowerShell job just crashed.

Error details

The background process reported an error with the following message: Unhandled exception. System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index').
