NOT WORKING: AWS sub-domain pointing to netlify Name server domains not working

Netlify site name - aspirerpsglearniverse.netlify.app

AWS sub-domain ‘aspire.rpsglearniverse.com’ points name server to netlify name server is not working.
a. AWS Configuration is attached in the post
b. Netlify setup also attached in the post

Intended flow: Once the user enters aspire.rpsglearniverse.com they should be shown website contents of aspirerpsglearniverse.netlify.app but the domain in the url section should be ‘aspire.rpsglearniverse.com

You should be adding a CNAME record and not NS records.
