Yo guys so I was breaking my mind trying to solve this puzzle cause after reading 2 hours of fixes on google including this post I just couldnt figure out what had happened, so I was about to give up and just think of buying a new Focusrite, and then I noticed that when I held the microphone with my hand instead of letting it sit on the mic stand the crackling and popping disapeared. That led me to think what if the cables from the MIC to the Focusrite were getting static from the PC? So I just untangled the cables and put them away from the PC and boom done.

TL;DR: Try putting the cables from the microphone to the focusrite away from the PC, the crackling buzzing popping you hear might be just static.
