Connect-MgGraph fails: Access to the path \u0027Local\\GraphPowerShellProtectedFileProviderInit\u0027 is denied

Describe the bug

I am trying to run a PowerShell script as a scheduled task. The script first runs a Test-DscConfiguration with a MOF file generated by the Microsoft 365 DSC module. During this test a connection to graph is established and everything works fine. But if I try to connect to Graph after the Test-DscConfiguration has finished within the same script, the connection to Graph fails:

Connect-MgGraph : The type initializer for 'Microsoft.Graph.PowerShell.Authentication.Common.ProtectedFileProvider'
threw an exception.
Access to the path \u0027Local\GraphPowerShellProtectedFileProviderInit\u0027 is denied.

This only happen if I run the script as a scheduled task, it works fine if I run the script in an interactive PS session on the same machine.

Expected behavior

Connect-MgGraph should work after Test-DscConfiguration has finished, also in a scheduled task.

How to reproduce

Run this as a scheduled task:

$test = Test-DscConfiguration -ReferenceConfiguration <path to mof file generated by M365 DSC>
Connect-MgGraph -ClientId <client id> -TenantId <tenant id> -Environment Global -CertificateThumbprint <certificate thumbprint>

Beginnen Sie damit, die Sequenz der geplanten Aufgabe mit Test-DscConfiguration gefolgt von Connect-MgGraph zu reproduzieren, und vergleichen Sie sie anschließend mit einer interaktiven PowerShell-Sitzung. Verfolgen Sie die Initialisierung von ProtectedFileProvider in Microsoft.Graph.Authentication.dll sowie den gemeldeten Mutex-Zugriffsfehler Local\GraphPowerShellProtectedFileProviderInit. Als erledigt gilt die Aufgabe, wenn Connect-MgGraph nach Test-DscConfiguration unter der dokumentierten Konfiguration von Windows PowerShell und SDK 2.25.0 erfolgreich ist.
