You want to change base URL using Commmand line, Run below command

php bin/magento setup:store-config:set --base-url="http://example.com/"

php bin/magento setup:store-config:set --base-url-secure="https://example.com/"

php bin/magento cache:clean

update:

 remove all content<magento-root-dir>/var*

Then run below command: remove all content(not remove .htaccess)/pub/static/* Then run below command:

php bin/magento setup:static-content:deploy

php bin/magento cache:clean

Then check it, if you have any issue let me know

You need to insert again "web/secure/base_url" and "web/unsecure/base_url", it's your store frontend URL (not admin).

Don't forget to clear your cache from command line:

php bin/magento cache:clean php bin/magento cache:flush

I've worked out how to fix this for our particular situation. It was a corrupt database table issue. So error from system.log file relevant is below:

main.CRITICAL: PDOException: SQLSTATE[23000]: Integrity constraint violation: 
1452 Cannot add or update a child row: a foreign key constraint fails 
(`gamefish_mag2`.`report_event`, CONSTRAINT `REPORT_EVENT_EVENT_TYPE_ID_REPORT_EVENT_TYPES_EVENT_TYPE_ID` FOREIGN KEY (`event_type_id`) 
REFERENCES `report_event_types` (`event_type_id`) ON DELE) 
in /var/www/vhosts/domain.com/httpdocs/vendor/magento/zendframework1/library/Zend/Db/Statement/Pdo.php:228

Restoring the report_event table to a previous version before the migration of product content from Squarespace from a month or so back did the trick. This product the product URL back to life and allowed us to add products to the cart again. Hope this helps somebody else one day for similar issue.
