@Grigory Kozyrev I think the error in this case is specific to your subscription or request. I am able to create a new compute instance without any errors from the studio.
Is this a managed account by a 3rd party with some restrictions? If Yes, you could reach out to the admin of the team to check if you have all permissions to create a compute instance.
If this is your personal account and since the details of the failure are not obvious, from the message you could report the failure screen shot of the request id by using the smiley icon on the top right-hand corner of the studio. This enables the service team who has access to your request details to contact you for any failures related to the service.
You also have the option to contact support team through Azure portal using the Help + Support blade for 1:1 support from a support team engineer.
I hope this helps!!
