Final Cut Pro Crashing - PLEASE HELP

Whenever there's a crash, reset your preferences by hold Opt-Cmd as you relaunch the application.

You should generate an EtreCheck report using full drive access from the application preferences. To produce a report use File->New Report. Then use the copy report function and paste it using the Additional Text button in the reply box.. The application is a free download from the App Store. 

There is an additional text button in the reply box. Next to the graphics button.

Did it crash again after resetting the preferences?

To add the report, click the “additional text “ button below the message area and paste it into the text box.
