Keyboard and mouse(internal and external) unresponsive/not working at login screen after a supposed fix

OK, -v should have instigated 'verbose' output!
Having done a little more searching and because you appear to have a dual boot setup, can you first try going into the BIOS and ensure that USB is set to Legacy mode and save changes on exiting BIOS.

If this is not possible solution, when you get to the login prompt can you get to a tty screen by using Ctrl+ Alt+ F3?
If you can login as your username with your password, then:

sudo apt-get install --reinstall xserver-xorg-input-all

and having just seen the xorg command reminds me that Zorin defaults to Wayland! aaaarrrrrgghhhh!

So before entering that command (if you can), disable Wayland by
following my guide here:

then run that xorg command given above.
