@Naveen1257,
let's try to find out your problem.
Can you please share with us the:
1. Error from the browser's developer tools?
2. Error from error.log
3. Error from Custom.log if any
Most likely it might be a case of a referencing resource that cannot be found, but let's analyse this situation.
If you wish to understand why I am asking for extra details from the list above, check out this blog, Basic Steps to Debug an Error in AEM, https://sourcedcode.com/blog/aem/development/basic-steps-to-debug-an-error-in-aem
