Hello @Komina ,
Thanks for reaching out to Microsoft Q&A platform.
It seems you have pasted only part of the error message. The error message might have also displayed the corresponding constraints . Take a look at those constraints. Check out the error code

For example constraints might be
OverconstrainedZonalAllocationRequest;
Provisioning state error code ProvisioningState/failed/OverconstrainedZonalAllocationRequest

In general those error means you might be using multiple constraints to deploy the VM.
Those constraints might include :- Networking Constraints such as Accelerated Networking or IPv6 , Availability zone , OverconstrainedZonalAllocationRequest , Ultra Disk capability , etc.

Below articles should help you out:

Sometimes retrying the same deployment should help out !

If you need additional help , please provide the SubscriptionID , exact constraints error code displayed in the error message.

Shiva.
