Only the customer has no response from the browser on a particular page. How to find the reason?

A project that uses vue cannot reproduce problems in both test and production environments. The
user cannot be reproduced in the test environment, only in the user"s chrome and in the production environment will occur browser non-response on a particular page.

because we can"t reproduce the problem ourselves, we can"t find any clues after reading code carefully.
ask the master, where should we start when we encounter such a problem? How to find the cause of the problem?
in addition, where do I start with the fact that the browser is unresponsive?
