I am unable to use my subscription when running an mg deployment command like. az deployment mg create --name $name --location $location --template-file $file --management-group-id $mgid --parameters networkingSub=$networkingSub.

Describe the bug
I am unable to use my subscription when running an mg deployment command like. az deployment mg create --name $name --location $location --template-file $file --management-group-id $mgid --parameters networkingSub=$networkingSub. The subscription is created using bicep.

Even when running the command to register my networking subscription with the networking resource provider using az provider register --namespace 'Microsoft.Network' --subscription $networkingSub, I still face this subscription is not registered with NRP error even with retry logic in place. When using other resource provdiers like az provider register --namespace 'Microsoft.AnyType' --subscription $subscriptionId, I have no issues and the registration happens without fail.

To Reproduce

1. Create a subscription using bicep.
2. Try to interact with this subscription by adding it to a Management Group and deploy some networking resources in a resource group underneath this subscription.

Expected behavior
The Microsoft.Network resource provider should register without issue and I should be able to deploy networking resources underneath this subscription.

When using Azure PowerShell I see the expected behavior when trying to register this subscription with the Microsoft.Network resource provider. No issues are faced with Azure PowerShell and no retry logic is needed.

Set-AzContext -Subscription "$networkingSub"
Register-AzResourceProvider -ProviderNamespace Microsoft.Network

Environment summary
Locally deployed using Windows.
