Hi,
Before entering the commands, please make sure the sandbox resource group name is updated in the exercise. For example, the first command should have resource group name similar to the picture below (your resource group will have different text after learn-):
When you entered the az vm create command in the cloud shell window on right, what is the precise error message and/or text output?
Before trying again, you will need to activate another sandbox since your previous one has expired by now.
Thanks.
