Final Cut Pro 11 issues on M1 Max Macbook Pro (transform effects, audio effects, freezing)

here's the 2nd etrecheck report. i actually tried fully uninstalling NordVPN and reinstalling without activating the threat protection, because i don't actually use that feature. and I cleared up as much space as I could immediately. and I went through and removed all of the google/keystone files and uninstalled chrome, and reinstalled FCP 11.

by "the issues are still there" I mean that all of the bugs that I described earlier are still present. (don't have time to record a video)

• when I copy keyframed attributes from one thing (for example a title), and attempt to paste it to multiple other things, it does not apply the effect properly to all of the other things (for example multiple titles). Usually I am doing titles that match up with the audio, and am attempting to make a title "pop" effect using "scale" keyframes. But it also applies to other scenarios. Usually one random title will pop properly and none of the others will do anything, because the keyframes have been applied WAY further down on the timeline for some reason (usually so far that the actual title does not extend on the timeline that far. and yes, I've also tried it while selecting the "maintain timing" option)
• When using certain audio effects, the effect has sometimes not functioned properly, and sometimes doesn't apply itself within Final Cut Pro, and if it DOES, it then often does not apply itself within the final exported file
• FCP often freezes, and I have to force quit
• FCP crashes more than it used to

when testing, I don't have any external hubs or second monitors or keyboards/mouse/trackpad, etc. Only the MBP and external SSD

And yeah, I did all that you said there. If something is failing in the machine, why would it only seem to effect Final Cut Pro? I haven't noticed issues in any other programs. Also, is there anything that can be done if something is failing?

It's unfortunate if that's the case because I think this issue started a couple months after purchasing this computer, but I never attempted to troubleshoot originally because I assumed the issues would be fixed in future FCP/OS updates

after examining closer, it appears that the issue with transform effects is only when there are keyframed effects, and it appears that the keyframes are still applied to the clip, but way further down on the timeline (even though the clip does not currently extend that far), and even if i select to maintain keyframe timing, I still have the issue.

I think that showed up after I had already restarted, but I restarted again to be safe, and still have the issue unfortunately. I may try deleting all of my Final Cut Pro plugins (I don't have many) and see if one of them are causing the issue for some reason

after deleting the plugins, I still have all of the issues. I've also gone through and made sure to update other apps and drivers on my computer, which didn't have any effect either. not really sure where to go from here besides wiping the computer entirely, but that seems excessive

UPDATE: Not good news. I got fed up with nothing working and used the "Erase all Content and Settings" feature to completely wipe my computer after backing up my user data to an external SSD (didn't solve the bugs) then I reinstalled the Operating System (still didn't solve the bugs), so now I am left with a totally "fresh" computer that has been reset to all factory settings, but the bugs and issues still persist within Final Cut Pro 11.

So at this point if anyone has any theories about what the issue could be, or any steps I could take from here, that would be greatly appreciated, but as far as I am aware, there isn't really anything else I can do...

I haven't migrated anything from my backup yet. I've left it totally clean while i'm testing it out.

I contacted apple support today and they were stumped too, but they suggested i could try installing the original operating system that the computer shipped with (monterey), and if it works then i would at least known that it's an issue with the OS and/or FCP.

I downloaded a version of Monterey from the app store, but i need to go out to pick up a flash drive or something to create a bootable drive, because for some reason there isn't an option on apple silicon to download a previous OS using a recovery startup

So i will see how that goes tomorrow

The issues i've been having have persisted through multiple FCP and OS updates.

I was under the impression that if i try to download FCP it will download the last compatible version?

I think their idea was to test out an old OS and FCP to see if it works which would then at least show that it's some issue with the updates of either the OS and/or FCP

To be honest i wasn't sure it made total sense either because it doesn't seem to be a widespread issue from what i can see online, so part of me is doubtful that it has to do with OS or FCP updates, but i guess i'll see.

Even if it is, i doubt they'll ever fix it in an update because i've had these issues for over a year

So I tested installing a fresh macOS (Sequoia) on an external drive, and doing everything else you mentioned, and the issues are still there even when booting from the external drive.

I also attempted to install Monterey (the internet and apple support said it is the OS my laptop shipped with) on a different external drive and see if that made a difference, but was unable to get a successful install for some reason.

What I then did was attempt to use Disk Utility's "First Aid" feature on the computer, just to see what would happen... nothing. Then I fully erased my computer again, but this time using Disk Utility, instead of the "Erase All Content and Settings" feature. After doing that, the computer had me install Sonoma (maybe that was what the computer shipped with?? can't remember when exactly I bought this, but that's possible. The most recent OS I had was Sequoia), and I tested everything again... the issues are still there.

Not sure what else I can do at this point. to me it seems like it is likely an issue with apple's OS/FCP, but I don't know why more people don't seem to have these bugs. Idk if it's even possible that my computer could somehow have an internal hardware issue that would cause this, especially considering the bugs weren't there when I first got it

I also tested out my old 2016 MacBook Pro that was running Monterey, and an older version of FCP X, and had no bugs
