"Unexpected Error" when creating a video creation assignment for students

Hello,

A teacher in my school asked for my help, but I do not have an answer for her. Does anyone have any suggestions?

The problem in our district subscribed Adobe Express on Chrome, Windows 11 Dell 3310 2-1.

"I am trying to have them create videos. I went through, set up my class, and tried to add the assignment. I put in the directions, gave a title, set the due date, selected a template, and provided instructions. But when I go to assign the video it says "an unexpected error occurred. Try again." I can't find any other reason for why the assignment can't be created. Am I missing something in the steps?"

Thank you so much!
