Clips Project iCloud Problem

Hello dear Community,

I have been working with Clips to create a Travel Videolog. Went in, recorded a new Clip ( Two for each Day ) and closed Clips again. When I opened Clips this morning, to add another video, an iCloud download symbol showed up in the upper right corner of the project. To continue working on the project I taped on it and after some time a prompt shows up that says : "The Project cannot be downloaded. A problem appeared while downloading. Try again later." (translated from mother language)

This prompt has an "ok" button only.

I really would like to make that project work again or regain the clips.

I hope you are all well and that somebody may have an idea for this problem.

Thank you for your time and attention, take care!
