Can you navigate to WooCommerce > status > scheduled actions > pending. Then please try to manually run the pending actions. Give it some time after that, and check again to see if the issue persists.
These pending actions are cron jobs that use WordPress WP-Cron to function. Sometimes, the cron jobs are not executed properly due to troubles with servers.
I would suggest manually hitting the Run button. The actions would get completed, and you won’t see them again.
