Lesson URL redirects to Course Page

Every time I press start course, the page redirects to the course page without loading the lesson.

Example:

I will click “Start Course” on the following page /stm-courses/COURSE_NAME, It is meant to lead to /stm-courses/COURSE_NAME/5528 but will not load the page and will automatically redirect back before I can even see the URL

This issue is for both paid and free courses with an admin account or otherwise
