The copper pad is out of the pcb, still soldered to the hotswap socket. So your pcb trace with this pad is broken.
First step is to glue the pad in place against the pcb with 2 parts epoxy glue.
Then solder a wire from this broken pad to the broken trace, or more easily to the pad of the next component that the broken trace connects to (diode or other hotswap socket)
thank you! i got some wire coming
