[BUG] Microsoft.Graph and PnP.PowerShell conflict (Could not load type 'Microsoft.Graph.Authentication.AzureIdentityAccessTokenProvider')

[nicole-ge]

Describe the bug
When using the Microsoft.Graph and PnP.PowerShell module in the same script

fails with the following exception:
Could not load type 'Microsoft.Graph.Authentication.AzureIdentityAccessTokenProvider' from assembly 'Microsoft.Graph.Core, Version=1.25.1.0, Culture=neutral, PublicKeyToken=315'.

The error occurs if the script is executed locally as well as an Azure Automation runbook.

Using module 2.4.0 | PnP.PowerShell in Azure Automation

Hi @gautamdsheth

Thank you for your answer. This bug seems to concern a lot of people and we have no workaround for it. How can I help to solve this bug? Please let me know I need to work with pnp and graph in one powershell script within one runbook

Seeing the same issue, my DEV VM is Windows 11 and has the following installed

PowerShell Version: 7.4.2
PnP PowerShell Version: 2.4.0
Microsoft.Graph Version: 2.18.0
Microsoft.Graph.Beta Version: 2.18.0
Microsoft.Identity.Client: 4.53.0

The error happens in the following line of code

$eid = get-mggroup -consistencylevel eventual -search $groupSearchTerm …
     | Could not load type 'Microsoft.Graph.Authentication.AzureIdentityAccessTokenProvider' from assembly      
     | 'Microsoft.Graph.Core, Version=1.25.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

Consistently happens when I'm running the script via VS Code Terminal Window (Powershell 7.4.2 process) or from my Terminal Window (PowerShell 7.4.2)

if you run the Graph stuff in a separate runspace (in my case a job), then you can circumvent the issue.

It's not a fix, but a workaround.

I hope there is a resolution soon.

#3637

They had 1 Delete the 125 file Microsoft.Graph.Core.dll from Modules PNP.Powershell Core Folder
but some modules like Get-PnPSiteTemplate have a hard coded dependency to 1.25
which i guess is why it has not been fixed for so long overall

Another was to do all the MG work first to force it to load the native Microsoft.Graph.Core.dll first
but that too seems to fail to allow MG run after any PNP occurs
PNP unloads the real Microsoft.Graph.Core.dll and breaks all MG as soon as PNP commands are run
