Is that a split outlet? In other words, does the switch control one half of it and the other half is on the other circuit? If so, I have your solution.

The circuit that the switch is on was designed to terminate at that spot. With the power and the switch on, find the hot wire for that circuit. Then, connect that pair to either the top or bottom of the outlet.

With the remaining two pairs, you’re going to have to make two pigtails. Take a spare piece of black/white wire accordingly and cut off about 9-10”. Strip the ends and with a wire nut, bundle the two black wires in the box together with one pigtail, and do the same with the white. Connect the other side of the pigtails to the open half of the outlet accordingly.
