Imovie lost!

I was completing a project after working on it fir four days. I composed a song on Garage Band, transferred it to Imovies, started working on it, paused to log on to Zoom. Afterwards, i diwnloaded KEYNOTE to add credits at end of of imovie. However, when I returned to the project it was gone. The title of the project is showing, but there is no film.

PLEASE TELL ME WHAT HAPPEND TO MY PROJECT. What would you suggest? Do I need to go and solict Apple Care to help me find the movie? Again, the title is there but no movie. Please help. Is there a glitch we should know about? I'm not the only one dealing with this predicament. And, imovie has frozen on me several times. This is my first time using imovie on my new IPad.

Thank you.
