iMovie not enough disc space
To fix the iMovie "not enough disc space" issue I did as someone suggested on this forum and put iMovie in trash without emptying the trash so I could upload a new iMovie from the App store. Unfortunately when I put iMovie into trash it automatically deleted it. So I would not suggest anyone doing that. Apple should remedy this iMovie issue already. Such a waste of time trying to do anything with iMovie these days.
