No Title Inspector Pane Visible

The application and its keystone components run actively whenever they’re loaded, flooding video toolboxes and seizing system resources. Those components frequently damage pro applications. They are often a cause of problems. If you don’t want to try it don’t. I offered a suggestion that has been helpful to others with similar issues, and I believe that unusual one specifically a few months ago. It may not work, in which case you can simply reinstall Chrome.

What FCP version is this?

That's not where the Titles browser appears. It appears in place of the clips browser. You should not be able to have the library and the Titles browser active at the same time.

Try trashing your prefs to reset the application.

If this is FCP 10.5.4 and you've reset your prefs (holding command and option while launching), then post an EtreCheck report. Click the "Additional text" button below and paste. Make sure to give Etrecheck full disk access.

You could also drag FCP into the trash (but don't empty it), launch the AppStore app and login with the AppleID you used to purchase FCP, click your name at the bottom left and re-download FCP. The latest version for Catalina is 10.5.4, which is what you want. 10.6 has some problems so don't upgrade to it yet.

You should try to do a complete uninstall of Chrome and the keystone daemons and reinstall the application. See chromeisbad.com for details.

If you need a browser that uses the same render engine as Chrome, try Edge.

I use Firefox as my alternate browser.

@budoman, thank you for coming back to post your findings. I would say what solved the issue is by completely removing Chrome you prevented it from being able to damage the freshly installed FCP.
