Stop.

Think.

Now explain properly in FAR more detail.

Is the popping/crackling sound heard when you are playing the guitar unplugged, is it heard through the amp if you are plugged in, are you plugging into an audio interface and using a virtual amp as a plug-in?

What have you tried to do already to identify the problem?

I pointed this out when you asked your last lazy question and you haven't learned.

Is it about a bicycle?

hey man! thanks for the reply. the noise occurs when im plugged in, to an amp and direct to my interface as well.

its more of a "static" sound. I think that better describes it than "crackle" or "pop".

It is very likely to be static. There are a range different plastics used for scratchplates and pickguards, and some are very prone to a build-up of static electricity when you move your hands over the guitar.

I believe you are talking about a Strat-style guitar here.

The best way to stop the noise is to cover all the underside of the scratchplate with copper shielding foil or tape (might as well do the cavities as well and get the full benefit) and make sure that the foil is all properly connected to the signal ground,

There is normally a triangle of foil under the pots on Strat-style guitars, but this is often plastic coated and sometimes there is no physical connection between the foil and the metal of the pots. So any build-up of static on the scratchplate isn’t dissipated to ground but jumps to other bits of the guitar which gets picked up by the pickups as noise.

So I’d take all the controls off the scratchplate and fully cover the underside in copper foil. As it is uninsulated, it should have a good path to ground through contact with the pot casings.

Lots of videos on YouTube about foil shielding cavities.

You can get self-adhesive copper foil on Amazon or eBay cheaply, as well as DIY stores, and it is often sold as slug-repellant tape. Typically under £10/$10 for a 1” wide 30 metre roll that will do several guitars. Just make sure it states that the adhesive is conductive.

You can pay a lot more for bigger copper sheets which look neater but do exactly the same job and often require soldering between sheet joins for continuity.

I’d also check whether the string ground wire to the trem claw is fitted and intact. If not, fitting one or repairing it could solve the problem, so check that first.

As Wonky says, definitely make sure the earth from the spring claw or bridge is connected to the electronics earth before doing anything else.

If your guitar has a plastic strat style pick guard the other thing that can help dissipate the static at least temporarily is using a tumble dryer sheet (pick any brand) and rub it over the plastic guard. I do this with the back plate on Gibson guitars as well. Works like magic.
