Hello Capstone
Welcome to Microsoft Q&A Platform, thanks for posting your query here.
It looks like the resource group deletion is blocked because there are resources within the resource group that are protected from deletion.
Based on the error you have shared, looks like the storage account named tejas761
is preventing the deletion of the resource group.
First you need to delete the storage account (tejas761) within the resource group.
Once the storage account is deleted, you should be able to delete the resource group without any issues.
Hope this helps.
