Update:

Answer 1

use 127.0.0.1 instead of localhost.

UPDATE `core_config_data` SET `value` = 'http://127.0.0.1/zain/accessories/' WHERE `core_config_data`.`path` = 'web/unsecure/base_url';

UPDATE `core_config_data` SET `value` = 'http://127.0.0.1/zain/accessories/' WHERE `core_config_data`.`path` = 'web/secure/base_url';

http://127.0.0.1/zain/accessories/ in this write your frontend url (home page url) what you have

after that run command in your terminal

php bin/magento cache:clean

Answer 2

You also can try to set correct domain in path web/cookie/cookie_domain in core_config_data table. (it's domain name, so no http(s):// and no / at end)
