Steps to reproduce

When creating a form and then registering an SPMT migration, Powershell freezes completely rather than prompting for credentials. This happens across multiple systems and environments.

Example of commands to replicate:

Add-Type -AssemblyName System.Windows.Forms
$form = New-Object system.Windows.Forms.Form
register-spmtmigration -migratewithoutrootfolder -force

Expected behavior

Prompt for MFA to appear

Actual behavior

Powershell freezes indefinitely
