I am posting this to get this into the search engines. I am hoping to hear from others that have had this same issue, and might have a solution.

I recorded 360 video (7680×3840) using Insta360 X5 and a DJI Osmo 360 cameras. I export the 360 video out to a flat video file using Insta360 Studio or DJI Studio desktop apps. I then bring this in to Final Cut Pro for editing. I have been doing this for years with no problems.

A few months ago, I went to make a new video. I found my project, that worked fine last year, now crashes Final Cut Pro. Sometimes it crashes on opening the project, sometimes when clicking around, sometimes it works for 15 minutes then crashes when I click on a view icon, etc. Very random.

I tried making brand new empty projects and recreating my template manually. Still crashes.

I eventually reset my macOS and then restored from a Time Machine backup. Even this “clean” reinstall still crashed.

I spent an hour or so on with Apple Support and we never figured out what was causing it, but we could even make it crash using only template items built in to Final Cut Pro — none of my graphics, video, or audio files.

The next test was to install a fresh copy of macOS with nothing else on it. I logged in to my Apple Store account and downloaded Final Cut Pro — the only app on this install of macOS.

And I can still get that to crash.

It looks like some bug with 360 video and the current Final Cut Pro, or some issue with the current macOS version.

Anyone encountered this?
