I am trying to restrict user to create a Story when Release Start Date is past in Jira Automation.
Basically I need to lock or block user to create a story tickets, no additional stories are allowed after Release Start Date
You cannot use automation to block or lock a user from creating an issue. Automations runs after the issue is created. You would need something like Scriptrunner or other Marketplace apps that extends the workflow so you can add a condition to prevent the user to submit the issue. When I was on Jira DC I used Scriptrunner to do something similar.
