FCPX lost sound effect library
After recent updates to everything, it seems that FCPX has lost all the sound effects again.
I've read through this thread https://discussions.apple.com/thread/251264172?page=2 and tried everything except a full MacOS re-install.
Has anyone come across any solutions that aren't quite so drastic?
