Hello, @Manish Gupta,
There is a possibility that a third-party plugin conflicts with the AMP plugin and causes the issue. Please try to disable all the third-party plugins (including cache plugins), that do not come bundled with XStore https://xstore.helpscoutdocs.com/article/36-included-plugins clear the cache of the browser, and check then. Maybe one of the additional plugins is the reason for the problem.
OR simply try to deactivate the AMP plugin on your site and check back.
And if the issue will still persists then please remain all the third-party plugins deactivated on your site and provide me the login access to your site in the below-listed format in the private content area and allow permission to debug your site which includes deactivating all the third-party plugins and on-site Customization as well so that I will check and assist you accordingly.
