Final Cut Pro X constantly crashing whenever I tried to edit clips after updating to Ventura

Please run Etrecheck and post its full report here. Use the "additional text" button and paste the report into the text box.

And don't forget to always delete the preferences whenever there is a crash.

In addition to Luis' request, which is essential, could you tell us something about your library, how many events, how many clips, how many clips in the events? There is a known issue with the OS with complex library structures. The behavior is dependent on the specifics of your system.

As Tom said, this is significantly related to library complexity, especially the number of clips in events. However, it does not indicate FCP is inherently unable to edit large projects using complex libraries. I have used FCP on libraries with 8,500 clips spread across about six events and another one with 5,000 clips in one event. It was relatively reliable.

This is a new problem that either began on Ventura 13.2 or got worse on that version. It is related to library complexity and can be identified by stack trace in the crash log that repeatedly lists this class and method: -[NSView _informContainerThatSubviewsNeedUpdateConstraints]

The crash log can be viewed using the Console app and clicking on "Crash Reports" in the left sidebar. Then, select Final Cut Pro in the middle pane, and in the lower pane, scroll down to see the log.

They are also in ~/Library/Logs/DiagnosticReports. They have a .ips suffix but can be viewed with Quick Look (select .ips file and press the space bar).

The only workarounds I'm aware of are reducing the number of clips per event to less than 300, removing Ventura 13.2 and installing 13.1 or even Monterey. Obviously, that is not possible on new machines that shipped with Ventura.

A few days ago, I filed a bug using the MacOS Feedback Assistant app, which included a simple replication scenario. I believe Apple knows about this and is working hard on the problem.

I am having this issue on my Macs as well. Ever since I updated to MacOS Ventura 13.2 on my M1 Pro MacBook Pro & 5K iMac (2020) Final Cut crashes randomly every time I open it. I have tested various projects on various external SSDs as well as projects on my internal SSDs, yet it still crashes every time.

I even tried uninstalling FCPX on both machines and reinstalling, still crashes.

I am just glad I am not alone in this issue.

Is the crashing caused by the issue joema described in detail? Can you work around it by reorganizing your libraries into more events with fewer clips in each?
