C1_W1_Lab_ unable to cetare Sagemaker Domain in AWS

Hello connections, Please guide me For Course-Analyze Datasets and Train ML Models using AutoML Lab 1 of Week 1. I successfully started the lab in AWS, but while creating NEW Domin in Sagemaker, it is just showing me a buffering sign… nothing is going onwards… On that page of new domain creation for Sagemaker- it shows “Access Denied”.
I refreshed and restarted the lab so many times… but the same thing happened.
