Not enough disk space for iMovie on Catalina
My MacBook Air was just upgraded to Catalina and now when I try to add music clips to an existing project in iMovie, I get a message that says "Not Enough Disk Space: There is not enough disk space at the selected destination. Please choose another one or clear some space." My computer still has over 100 GB of space available so I know it isn't that. How do you get past this so I can do work in iMovie?
MacBook Air 13", macOS 10.14
