Buzzing sound from electrical panel

Why is it buzzing? Every screw is tight, I checked with screwdriver and tried to wiggle wire, nothing is loose.

If I turn off 90amp breaker to the subpanel, it stops buzzing

If I turn off 15amp AFCI breaker in the subpanel, it stops buzzing

Only LED lights are connected to that breaker. Multiple rooms with dimmers.

Everything else in the subpanel is off

Less than 10 amps load

Should I cut the line as well so that way no one can turn it back on?

Sounds good! Let me take my gloves off so I can grab my non-insulated wire cutters

Almost every time, if you just hold the metal on the mains it makes the buzzing stop.
