Snap, Crackle, and Pop (Bass Making Crackle Noises)

I've been noticing a residual crackling/fizz noise from my bass. I originally figured it was a bad battery, but I just changed batteries like 3 days ago and it's still there.

I've done the usual assortment of basic troubleshooting and it's definitely coming from the instrument itself.

From my time jamming recently, I've noticed a few things. When I physically shake my bass in a certain way it'll make some crackles.

There are more overtones than usual and the bridge pickup as a sort of microphonic quality to it. It picks up the sound of my finger when I give it a tap or two (looking back it always has, but is definitely worse as of late.)

Pickups also seem more sensitive to my phone when in close proximity.

If you'll reference the picture below, you'll see a pink arrow/circle. Not sure what you call that, but when I put my finger on it, there's a noticeable increase in the noises. For reference, I touched the other ____ (thing), with the blue circle around it, and there wasn't peep. I'm assuming these are pickup related.

Do I have a busted bridge pickup? Or could it be something else?

I'm playing a Warwick GPS Streamer LX with active electronics.

Apologies for my lack of terminology, I'm learning things as I go.

I once had a cracking pickup. In took it out as part of my trouble shooting and turns out some moisture must have gotten behind it and one of the wires had corroded where it enters the pickup. Ended up just replacing the pickup and it resolved it.
