Ripping Models from splatoon 3

[John1414]

I am trying rip models from splatoon 2 and 3 using hactool, but i am running into issues. I have keys, that should work, but when I run hactool it finds the files in the nsp, but then gets a "Failed to read file!" after the first 3 and exits. Alll the guides an can find for hactool are at least 3 years old and i cant find this issue in any of the ones i have found.
So i suppose i have 2 (and a half) questions:
Is hactool still the best method for ripping assets from switch nsp's? (if not, what is used now?)
If hactool is the main method still, how do i fix this error and what causes it?
Thanks for any help.
