How to import projects from one library to another manually? (Through package contents)

Since you're a long time FCP user, you most likely tried this but just in case: Did you reset FCP prefs?

Did you try deleting CurrentVersion.flexolibrary? This can *sometimes* fix a broken library. Work in a duplicate of the library.

Quit FCP

Make a duplicate of the library

Open package contents

Delete CurrentVersion.flexolibrary

Open the library in FCP and see if behaves better

I’ve been a Final Cut Pro editor for 10 years and I’ve never run into as big a problem as this one.

Final cut crashes upon loading a specific event in my library. I’ve troubleshooted to a point where I know that no sole project is the culprit (tried opening after deleting the projects 1 by 1), neither the render files (trashed).

I have no recent backups of said library either, so that isn’t an option.

Are you sure about that? Final Cut Pro makes automatic backups when you use the library.

They are stored by default in subfolders of ~/Movies/Final Cut Backups

These backups do not have the media, but if you find a backup that opens, we can work toward relinking that media.

You can also use the Arctic app to delete render, proxy, and analysis files (all of which can be rebuilt) without opening FCP at all. I've found that to work on occasion.

Even if you don't have a recent backup of your library, you can re-edit it if you have an old one. Do you back up your library with Time Machine every time you finish working?
