Are you using a chain wrench/chain whip? The lock nut should be a standard thread (meaning turn counter clockwise to loosen) but you need to hold the cassette still with the chain wrench.
I like to hold the two about thirty degrees apart and grab both with one hand and squeeze while using my other hand to hold the tool in place.
Yeah I have a chain whip. I’ve previously only done HG hubs but this tool just doesn’t seem to be seating well when I try it. It’s a pretty old bike so maybe I just need to persuade it in to position more before I try to turn it. Might get the cheater bar out of the stand tomorrow perhaps
