iMovie Project not Opening in iPhone 13 pro

I created many video projects in iMovie, most recently there has been a delay while editing. I tried to delete the app but lost all of my projects, I did the hard re-start as well. I decided to start a new project with the same video. This time, I edited the project the entire way through, now iMovie will not open the project at all. I can add projects and the editing works but it is still glitchy with a delay while editing. I did the most recent update thinking it will fix all of this but still nothing. I restarted, and did the hard re-start shut down and still cannot open the project or fix any glitches. How can open this project?
