I'm using the Microsoft 365 version 2210.

Which version of Powershell are you using?
Loading the Assembly seems to work fine on Windows PowerShell/PowerShell 5 but it doesn't work for me on PowerShell Core/PowerShell 7

Yes using powershell 7. Will see if I can use the windows version, it makes sense if the module isn't Net core compatible and needs all the Windows apis to work.
