Issue Opening Studio from Rich Content Editor in One Course but not in other courses

[kehomi]

Hi everyone,

I’m having an issue with Studio in one of my Canvas courses.

Last week, I was able to open Studio from the Rich Content Editor and successfully upload a video to a page. However, when I tried again this week, every time I click on the Studio button, I only see a window with a cloud and three dots — and nothing loads.

Here’s what I’ve tested so far:
 - In my Sandbox course, Studio opens fine from the Rich Content Editor and I can upload videos without any problems.

 - In the affected course, the error occurs consistently on every page when I try to open Studio.

 - I tried copying the page from the course into my Sandbox to upload the video there, but the same error appeared once the page was copied ove

 - Also not working in incognito/private windows

 - Also cleared Cache & Cookies

From my testing, it seems like the problem is isolated to that particular course.

Has anyone experienced this before? Is there a fix or a setting I need to adjust in the course to get Studio working again?

Thanks in advance!
