The guitar has a Floyd Rose double locking system so unless the groove in the locknut is pitted I don't see how this can be causing the problem. Anyway, I'll try changing the string next and see if that helps.
I was just covering all basses suggesting the nut. as I didn't have enough info about your axe, but now that I know,, OH,,,,and,,,,, I have worn a floyd nut from years of extreme bar usage, and,,also have received a faulty nut direct from the company(which they replaced) that had some weird buzzing on the B string due to the way it was cast.
All my guitars(mostly Jacksons) are floyd equipped ,, that's why I said to also check the saddle, cause I have
definitely had this problem before, usually it was just a worn string thing right as it crests the saddle from the lock block(occasionally weird new string) but have also seen it being from
1) The string sitting in the saddle funny,,,like if it is not locked down in the block centered, and off a little to one side before it travels across the crest of the saddle.
2) The saddle being slightly cocked one way or the other, sometimes it isn't all that noticeable, but if you were to unlock the saddle they will definitely move from side to side.
3) In combo with 1&2 the intonation might be off, or have slipped a little.those little saddle bolts are infamous for that
BTW, is it an OFR or a licensed floyd? standard or low profile?
Hope some of that helped,, I
know how irritating that can be for sure
