Final Cut Pro 10.4.9 crashing on startup

Hey all,


I'm having a really rough time with Final Cut lately. It's almost like every week I have to reinstall this app. Basically union startup the app flashes open and then crashes. Does that for about 5 startups and then opens up and works fine. After about a week of use, it does it's normal 5 crashes and then it doesn't show video at all and the only way to fix it, is it delete the app and re-download it. I will post the crash log below if anybody can help. I'd really appreciate it.


-The crashlog only lets me put 100,000 characters so i'll have to post the rest if anyone needs it.

Make a list of all your 3rd party plugins and see if the developers have updates. Or, go the other direction and remove them and see if the launch problems go away. Reinstall (updated versions if available) one at a time to see which one (or more, as Tom says) might be causing your launch problem. Larry Jordan has a relatively recent article about removing plugins <https://larryjordan.com/articles/how-to-remove-plugins-from-final-cut-pro-x/>
