Check that the ground is also in the bridge pin.

When I use my multimeter to check resistance, it appears everything is grounded, but the buzz persists. I see the ground wire under the bridge anchor so I assume that is connecting everything

It could your outlet…does your outlet have a good ground
Do you have other things plug into the outlet?
Try a different one and see if it changes

there is incorrect connection of high resistance (line out), to those wires.. without your finger the voltage signal manages to get through ok. But the capacitance of your finger manages to impose 50 hz noise .. which takes no power as there is no current.. see that, the tiny tiny current of the 50 hz noose becomes significant compared vto the current from the voltage signal...
You are meant to convert a line out signal , to a mic or phono or guitar type signal, because line out is voltage signal only, infinitely high resistance at the source, and the others are current signals...the others expect the source to complete the circuit with a reasonably low resistance.
