SO MANY BUGS!! (unable to paste transform effects to multiple clips, audio effects fail on export, software freezing)

• I have been having these issue through many different versions of Final Cut Pro X, and they have persisted into the Final Cut Pro 11 Update (I am always using the newest OS and FCPX version, and I am using an M1 Max Macbook Pro with 64GB unified memory)

• When attempting to copy/paste transform effects of a clip to multiple other clips, it either doesn't work, or only applies the effects to 1 clip, and nothing is applied to the other clips. So I am forced to paste the effects to each clip individually which is extremely time consuming.
• audio effects sometimes do not work within the timeline. If they do work within the timeline, when I export the video, they are often not there at all. 
  • • my workaround for this issue has been to export the video as SOURCE Apple Prores 422 with Linear PCM audio (which successfully applies audio effects in the exported video), and then bring that video into the timeline to use it's pre-exported audio track in the final export (which is most often h.264, multi-pass, ACC, rec.709, .mp4)
• the program often freezes up, and I need to force quit and restart Final Cut Pro

I have only been able to find 1 or 2 other people with any of these individual issue online, and so far I have seen no solutions. The bugs constantly persist through every update, including this update to Final Cut Pro 11

I have tried resetting FCP to original settings, I have tried fully uninstalling and reinstalling FCP, and all of the issues still persist.

I have no clue what to do, and it seems that most people don't have these issues and are unable to recreate the problems.

PLEASE CAN SOMEBODY HELP!!
