student enrollment problem after purchase

Hi, I’m using Tutor LMS with WooCommerce integration.
Issue: Customer payment is successful, but the student is not auto-enrolled into the course.
Order status: Completed
User email matches WooCommerce order.
But enrollment does not appear in the Tutor LMS students list.
Please help check if this is a hook or integration issue.

This happen only to one of my student only..
