@Dsrygaard which version are you using? can you get latest version and try Install-Module -Name AzureADAssessment -AllowPrerelease

Solved by adding Add-Type -AssemblyName System.IO.Compression.FileSystem before running the script

I found the cause for this. It was only happening on Windows PowerShell but has been fixed now.
