Error Acquiring Token / Unable to load System.Diagnostics.DiagnosticSource

Good afternoon,

We've been receiving the following error when running Connect-PowerBIServiceAccount -ServicePrincipal after updating to version 1.3.80:

Connect-PowerBIServiceAccount : One or more errors occurred. (Error Acquiring Token:

Full command:

$password = ConvertTo-SecureString $clientSecret -AsPlainText -Force
$credentials = New-Object System.Management.Automation.PSCredential ("$clientId", $password)
Connect-PowerBIServiceAccount -ServicePrincipal -Credential $credentials -Tenant "$tenantId"

I have verified that this works with version 1.2.1111 of the module.

Start by reproducing Connect-PowerBIServiceAccount -ServicePrincipal with MicrosoftPowerBIMgmt 1.3.80 and compare it with 1.2.1111. Inspect the MicrosoftPowerBIMgmt.Profile module and its dependency packaging around System.Diagnostics.DiagnosticSource and the Microsoft.Identity.Client stack trace. Done means service-principal authentication works on 1.3.80 without the assembly-load error.
