Someone can help me to understand this problem

I create a fresh installation of Windows server 2016 but i always got the same problem

I notice that when in the debug output show that it's using the MSAL version 4.67.2.0 all works. I don't know how to force to use this version

Thank

Scenario

Other - please specify

Is this a new or an existing app?

The app is in production, I haven't upgraded MSAL, but started seeing this issue

Issue description and reproduction steps

On Windows server 2016 with powershell 7.5.0
Execute the command Connect-MgGraph

Relevant code snippets

Expected behavior

Command should connect to microsoft graph APIs

Identity provider

Microsoft Entra ID (Work and School accounts and Personal Microsoft accounts)

Regression

4.66.1.0

Solution and workarounds

No response

[gladjohn]

Can you check which versions of Microsoft.Graph.Authentication and Microsoft.Identity.Client (MSAL) are installed by running:

Get-Module -ListAvailable Microsoft.Graph.Authentication
Get-Module -ListAvailable Microsoft.Identity.Client

What version of PowerShell are you using?

$PSVersionTable

I am not seeing any specific errors in the MSAL logs you shared. how are you switching between MSAL version? Are you updating Microsoft.Graph.Authentication?

little more info on what error you are seeing? and more logs can help us.

Abount command: Get-Module -ListAvailable Microsoft.Identity.Client
I have no output

This server is a fresh installation of Windows Server 2016 x64. I installed only Powershell 7.5.0 and inside it i installed Microsoft Graph SDK through command Install-Module Microsoft.Graph -Scope AllUsers -Force
After that i installed another powershell module called SimplySql

I don't know why the MSAL version change on debug output. I have never installed MSAL on this server. I suppose is it integrated into the Graph modules or not?

There is a Powershell command that show all MSAL version installed? How to remove all old version and keep the last
