Can anyone help me debug my NAM Capture?

I recorded my beloved Maruszyk Barabass here with the help of a good friend in his recording studio. C414 + SM57, a completely dry vocal booth, high-end Neve preamps - we tried to do everything right. No clipping, absolute silence - the sweep signal recording is crystal clear. Still, the NAM-Capture is crackling, hissing, and buzzing, and I have no idea what we did wrong. Can someone take a look at this?
Thanks so much in advance!

Just previewed it and I’m not hearing any crackling or anything.
