Wuk Lamat is the perfect storm of voice actor limitations, bad direction, and bad writing.

The writing is pretty rough from the get-go, so it's going to hurt performance as well as potentially intensify dislike if you REALLY don't like the writing. Writing is bad and Wuk is the bulk of writing so Wuk is bad sorta deal.
The voice direction is, pretty clearly, rough. Speeeeeeeeeeeeeeeeeeeeeen comes to mind. There is no way in hell the director told the VA what was happening in that scene if that's the end result.
The voice actor as well is just limited. Let's call a spade. You have a relatively new voice actor with the natural complications that being trans can bring to the table in terms of vocal range trying to be emotional while also forcing an accent. That's balancing way too much and it just fails every time. I'm not going to touch on the allegations of Kate friend-hiring, or her not actually being Puerto Rican or whatever, I just don't think she's the right fit for the job. Not yet, not in this game. Side character for sure, main, 90%+ of an msq character? not so much.

I can't say for certain what needs to change. What I can say for certain is I didn't enjoy wuk lamat. At all. Please god give anyone else screentime I beg of you
