Emptying Trash Issues

Then try turning Screen Time off. Once the Trash has been emptied, then you can re-enable Screen Time.

If your macOS user account is one being controlled by Screen Time, then you likely do not have the necessary permissions to touch that file even when it is in the Trash.

Turn off Screen Time on your Mac – Apple Support (UK)

Have you tried rebooting the computer & trying again?

If so, then try booting into Safe Mode & try to empty the Trash.

you're welcome, :)

Check who actually owns the file.

Open Terminal and run ls -l ~/.Trash to see if the items belong to another user, a system process, or have immutable flags. If you see the “schg” or “uchg” flags, remove them with sudo chflags -R nouchg ~/.Trash/*. If the files came from an external drive, the drive’s permissions may still apply, in that case, reconnect the drive and empty the Trash again. And if Finder itself is stuck, you can force-delete with sudo rm -rf ~/.Trash/* as a last resort.

Once you know what’s holding the file (permissions, flags, or missing source drive), the issue clears instantly.

i think i would try temporarily disabling SIP. boot into recovery by holding "command+R" during startup. once there open terminal by clicking on "utilities" in the menubar and choosing "terminal". then paste in "csrutil disable" without the quotes. enter your admin password if prompted. then restart the mac and try to empty the trash. wether or not it works, make sure to re-enable SIP. boot into recovery again, reopen terminal and paste in "csrutil enable" without the quotes. enter your admin password if prompted and again restart the mac normally.
