Unable to create a domain in SageMaker Studio

Hello.

SageMaker domains default to two quotas per region.
https://docs.aws.amazon.com/general/latest/gr/sagemaker.html

Judging from the error message, there may be restrictions on your account, so I think it would be a good idea to apply for the restriction to be lifted in the region you are using from the service quota screen.
https://console.aws.amazon.com/servicequotas/home/services/sagemaker/quotas/L-B683BCB0

If this does not resolve the issue, I recommend that you open a case with AWS Support under "Account and billing".
Inquiries under "Account and billing" can be made free of charge.
https://docs.aws.amazon.com/awssupport/latest/user/case-management.html

As this is a new AWS account, your service quota may have a lower limit. Can you go to Service Quota console, Services, SageMaker, Total domains to Request increase at Account Level?

The link for us-east-1 region is https://us-east-1.console.aws.amazon.com/servicequotas/home/services/sagemaker/quotas/L-B683BCB0
