Hi. I am on a 2019 13" MacBook Pro 500 GB (Specs in attachments) and FCPX has been kind of buggy for me. I have been editing off of an external hdd (WD MY PASSPORT 2TB), and every time I try to edit a video over, like, 30 seconds, my library "is broken" and I need to work off a backup. No big deal. Right? WRONG!! It then crashes on me, and I have to do the ENTIRE YouTube video over again. I don't have any extra plugins or extensions installed except for titles and transitions I made in motion, and a title/transition pack from dp669 (Youtuber pack 3.0 https://www.dp669.com). Can anyone help or has anyone have been having issues? Thanks.
