Conflict between Microsoft.Graph and PnP.PowerShell Modules in PowerShell Extension

[IoannisGianko]

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

I'm encountering an issue when using the Microsoft.Graph PowerShell module in combination with the PnP.PowerShell module while connecting via a certificate. The issue only occurs within the PowerShell Extension terminal in VSCode.

Expected Behavior:
The command should execute successfully without any errors.

Actual Behavior:
After connecting, any attempt to run a MgGraph command results in the following error:
Could not load type 'Microsoft.Graph.Authentication.AzureIdentityAccessTokenProvider' from assembly 'Microsoft.Graph.Core, Version=1.25.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

Notes:

• The issue does not occur if the PnP.PowerShell module is uninstalled or downgraded to version 2.2.0.
• The issue is only present when using the PowerShell Extension terminal in VSCode. Opening a standard PowerShell terminal within VSCode does not produce the error.
• I have tested this across multiple machines, and the issue persists.
• Installing PnP.PowerShell v2.2.0 resolves the issue.
• Opening a standard PowerShell Core Terminal, outside of VsCode, does not produce the error.

Is there a known incompatibility between these two modules in the PowerShell Extension, or any workarounds besides downgrading the PnP.PowerShell module?
