The course is an H5P video, displaying an error

Hello,

Thank you for reaching out!

By default without any extra plugins, the LMS supports the following options to upload a video to lessons > HTML, Youtube, Vimeo, External video link source, Embedded video source, shortcode sources, and presto player. For extra info, please check it > https://docs.stylemixthemes.com/masterstudy-theme-documentation/lms-courses-features/how-to-add-a-video-to-the-lesson

Can you clarify how you added H5P video? What type you used?

Best regards
