Imovie crashes every time when trying to open
i'm finding myself unable to open Imovie at all when i click on it... it opens with the loading box running through libraries then just crashes. i've tried following advice on previous threads but nothing seems to be working. my mac is running 10.13.2 and i'll copy all the sections of the report that it will let me post that keeps popping up below. if anyone has any ideas i'm all ears!
