URGENT: cronjob scheduler not running automatically

Hi,

URGENT HELP REQUIRED

We have updated the WordPress and woocoomerce (5.1.0) versions. Database has been updated successfully as well. But the cronjob scheduler is not working automatically. Like action_scheduler_run_queue action has to be run every minute but it is not running.
WE have following in our wp-config.php – define(‘DISABLE_WP_CRON’, true);
We have also deactivated all the plugins and then activated them.
Also, if I run action_scheduler_run_queue manually, it runs the scheduled actions. But it should be run automatically.

Can you please help??
