@Zohaib Nasir how are you providing the certificates? If you’re not using the defaults so, providing flags like

tls_server_certs

and similar, be sure to give them through the flagfile or the process arguments, not the config file. In 5.4.0 we enforce this, because they are CLI flags and shouldn’t be given or changed through the config file. You will also get warnings in the logs about them if that’s the case.
