Firstly, apologies for inconvenience this issue may have caused.

You may notice that some VM sizes are unavailable for certain subscription types in your region as it experiences high demand.
It could be related to the capacity issue. You can see more details in the below sticky thread for updates on this.

You can check to see if SKUs are available for your subscription in a given region by using the az vm list-skus command (as well as in the portal):

To overcome this issue, I would recommend creating VM in other regions.
