Initialize fails when using self-hosted agents and Managed Identity

[StefanIvemo]

Describe the bug

When using self-hosted agents and Managed Identity instead of service principal the initialize step fails. In my case I'm using VMSS.

Steps to reproduce

1. Deploy self-hosted agents and enable Managed Identity. Configure new Agent Pool and update pipelines to use the new pool.
2. Update the connect step in sharedSteps.yml to: Connect-AzAccount -TenantId $(ARM_TENANT_ID) -SubscriptionId $(ARM_SUBSCRIPTION_ID) -Identity
3. Run Pull pipeline.

Screenshots

Initialize will fail on Invoke-AzOpsPull.

If I add Import-Module AzOps -Force to the initialize step I get the following error instead.
