Additional context

This same error is sometimes observed when executing the runbook on a hybrid worker.

No source file or test is identified. Reproduce the failure in an Azure Automation runbook using PowerShell 5.1 and Microsoft.Entra 1.0.10, then compare it with execution on a hybrid worker while investigating the module-loading OutOfMemoryException. Done means the runbook starts and executes commands such as Get-EntraUser or Set-EntraUserLicense without the startup failure.
