Thanks @t-p for your support ??

The issue has been resolved. Divi Page Builder was OFF on the course Pages.
Basically, I visited Divi Theme Options and Enabled Divi Page builder for Courses and Lessons

WordPress Dashboard > Divi > Theme Options > Builder

Thanks for your help @t-p

Thanks @t-p , Shall I ask the same question on that link. Actually I am using Divi and Tutor LMS on my other website too. There is no issue, and I recently designed that website.
That’s Why I am using these 2 for new website.
I will try to check what is the issue.

Thanks again for the info.
