How can we improve Azure Cloud Shell?

errors on azure shell while trying to create resource group in sandbox

The command is failing and not getting executed . I am getting the below error even when I run the exact command as provided

@Azure:~$ az acr create --resource-group cc95b2a3-a0c1-4891-ad1d-fb5101048c3b --name $ACR_NAME --sku Premium
The command failed with an unexpected error. Here is the traceback:
