Error Loading Extension and Definition in Azure Windows Virtual Desktop Deployment

I recently created a new Windows Azure trial account and have a problem deploying Windows Virtual Desktop. Each time I try to create a new host pool it will prompt me with the ErrorLoadingExtensionAndDefinition reason code. 

I have contacted Azure technical support and they suggested that I post this on the forum for assistance as this error has also impacted multiple customers. 

Here's the full error summary. Hope someone can help me find a workaround so that I can deploy Windows Virtual Desktop.
