My movie won’t export – iMovie Review

No matter what I do, the movie I’ve edited will not export! I have more than enough storage to save the creation, so I know that’s not the problem. Please fix this ASAP because I’m really trying to become a YouTuber and I rely on iMovie because it has everything I need to edit, but it won’t allow my project to be saved to my camera roll.
