Can't call New-PnSSite when Microsoft.Graph.Authentication is loaded

[Ambergahill]

Reporting an Issue or Missing Feature

When calling New-PnPSite and the Microsoft.Graph.Authentication module is loaded, you get an error saying "Could not load file or assembly System.IdentityModel.Tokens.Jwt Version 6.12.2.0

Expected behavior

The new SPO site should be created without error. Code is working fine when the Microsoft.Graph.Authentication module is not loaded

Actual behavior

See screenshot

Steps to reproduce behavior

1. Load Microsoft.Graph.Authentication module. Currently testing with 1.23.0 but I have tested other versions with the same error.
2. Load PnP.PowerShell module. Currently testing with 2.0.41-nightly, but I have tries other versions as well.
3. Connect to Microsoft Graph using Connect-MgGraph (not sure this step is actually necessary, but in Azure functions, it doesn't look like it loads the module until it sees you are using at least one command from that module)
4. Connect to SPO using Connect-PnPOnline
5. Try to create a site with New-PnPSite

What is the version of the Cmdlet module you are running?

See above

Which operating system/environment are you running PnP PowerShell on?

• Windows
• Linux
• MacOS
• Azure Cloud Shell
• Azure Functions
• Other : please specify

Moving it to discussion forum.

This issue is something related to loading external libraries in the same session as PnP PowerShell. This not something we maybe able to fix.

Hi @gautamdsheth I think this might be the same issue as reported in #3637. It seems that MgGraph and PnP are not compatible with each other in terms of authentication. Is there anything that can be done from your end? Microsoft is moving everything towards MgGraph (AzureAD is now obsolete) and this conflict has broken many of my scripts.
