Final Cut Pro crashes when I go to export/share

Did you do an iTunes update recently? There’s a problem with the mobile device.framework file. You might need to revert to the previous version of the file. Look through this thread for more information

I run an older system because my Mac seems to get slower when I update––a bit like what used to happen with iPhones.

I don't know what you did to try to uninstall it, but clearly AVG is pretty much still there, in bits and pieces:

Launchd: /Library/LaunchDaemons/com.avg.hub.schedule.plist

Executable: /Library/Application Support/AVGHUB/com.avg.hub.app/Contents/scripts/schedule.sh --ttl 14400

Launchd: /Library/Application Support/AVGHUB/com.avg.hub.app/Contents/scripts/com.avg.hub.schedule.plist

Executable: /Library/Application Support/AVGHUB/com.avg.hub.app/Contents/scripts/schedule.sh --ttl 14400

Start by deleting avg.

Any reason you are still running macOS 10.12 Sierra?

Your mac can run the current OS just fine,and you’re missing on many updates for FCP too.

I had AVG Anti-Virus and AVG Cleaner. I deleted AVG anti-virus but not cleaner. Could those launchd be the cleaner?

I am not familiar with details, maybe. Anyway, you don't need either, and cause nothing but trouble, for a false sense of security.

What cleaner? That word, associated with a mac, means trouble; but I don't see anything like that in the report.

If by the report you mean a crash report, it probably does not help.

Whenever there is a crash, the first thing to do is to delete the application preferences.

To delete preferences, hold down command and option while starting FCP X and click Delete Preferences.

The application will start in a default state, and open an "Untitled" library. Reopen the library you were working on, set the preferences the way you like them, and try again.

If the issue persists, there is a report that you should post here: the one produced by Etrecheck.

Download Etrecheck from the App Store, have it produce the report, then post here.

Click the "Additional Text" button:

and paste into the text box since, as you say, a long report cannot be posted directly in the message.
