Azure CLI lab command doesn't work in latest release(2.0.72)

I updated the Azure CLI recently to version 2.0.72 and now my scripts that creates DevTestLab VMs and apply artifacts don't work. I get the following error:

az : Command group 'lab' is in preview. It may be changed/removed in a future release.

An example command that worked previously but fails now is the following:

az lab vm apply-artifacts --lab-name 'OPX-Dev-Test-Lab' --name opx-azure-01 --resource-group 'OPX-VHDs' --artifacts '@\\officefile\public\cowen\AzureDeplomentScripts\removeAgent.json'

On another machine where I have an earlier version of the CLI (v. 2.0.64), the exact same command above works. Seems like something has been broken or changed for the 'lab' command in the latest version of the CLI
