FCPX quitting unexpectedly

Also, you have the devilish keystone daemons that are associated with Chrome:

[Loaded] com.google.keystone.agent.plist (Google LLC - installed 2022-04-19)

[Loaded] com.google.keystone.xpcservice.plist (Google LLC - installed 2022-04-19)

You need to completely uninstall those - see https://chromeisbad.com for an explanation of what they do and how to get rid of them.

After doing that, it is necessary to delete FCP and download a fresh copy from the App Store.

You failed to post the actual report. The text is only info about Etrecheck itself.

In Etrecheck, click Share Report->Copy Report, then paste into the text box as you did above

The first thing to do is to completely uninstall avast.

Going through the rest of the report, it says this about the crash of Final Cut Pro (and a similar one for Motion):

Details:

libcrypto.dylib: Invalid dylib load. Clients should not load the unver

sioned libcrypto dylib as it does not have a stable ABI.

libsystem_c.dylib: abort() called

I am not completely sure of the details, but I have seen this happen in situations where people have installed homebrew and some brew package that installs an old version of this libcrypto. Maybe someone else can help here.

You may want to search for libcrypto.dylib in /usr/local or /opt/local
