Final Cut Pro 10.6.5 keeps crashing with AppKit exception

My FCP X is completely unusable, just opening a project makes it crash. I'm not exactly sure when it started, but it might be when I updated macOS to version 13.2. I attached the crash report and the EtreCheckPro report as it seems to be commonly asked around here.

MacBook Pro 16″, macOS 13.2

There are other issues you should address. It looks like you did a full migration to the new computer, rather just the user and a clean install. There's a lot of old, obsolete stuff on the system.


You have CleanMyMac installed, hopefully you haven't run it on that computer. If not, use App Cleaner  https://freemacsoft.net/appcleaner/ to completely remove it.


Don't run Malwarebytes continuously.


Do a complete uninstall of Chrome and its keystone launch daemons. https://support.google.com/chrome/answer/95319?co=GENIE.Platform%3DDesktop&hl=en
