Trying to Rip Models from Multiversus

I'm currently using Fmodel and Unmodel, I think the problem is the encryption keys are out dated but I've never done this sort of thing before, I'm trying to rip Jason's model and animations for reference for a project I'm working on. Any help would be appreciated, I've seen people rip models from the game in the Multiversus Leaks subreddit so I know it's possible. Please do not post pictures of memes or people with stupid faces in the comments. I genuinely am asking for help, And I have done nothing to you to deserve this sort of unwanted behavior. Thank you in advance.
