I need assistance with saving a Form template I created correctly

I recently created using Microsoft 365 app Forms a template for a university assessment.  So it saved in Forms fine however when I attached it to the university assessment for marking I received a message back from the teacher advising that it wouldn't open .  Upon checking what they could see it only shows the title page and nothing more .  How do I save this so I can attach it properly and the entire form can be viewed by others?
