Restart your Mac

Firstly, restart your Mac and then try to empty the Trash again. Although you think that you have quit all apps that could possibly be using the file, maybe there is an app with one or more background processes that are still using the file. A restart can terminate the background processes.

• Hold down the Shift key when your Mac boots.

• Release the key when you see the Apple logo with progress bar.

• Then you can empty the Trash on Mac and restart your computer to exit safe mode.

Now the Mac boots up, empty the Trash. After you have done clearing the Trash, you're recommend to enable SIP again. You need to put the Mac into Recovery mode again, and this time use the command line: csrutil enable. Then reboot your Mac to make the command to take effect.
