Unable to get tree sitter to work

[CeNiEi]

Running Emacs 30.1 on MacOS 15.1. This is my init.el file

(require 'package)
(add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t)
;; Comment/uncomment this line to enable MELPA Stable if desired.  See `package-archive-priorities`
;; and `package-pinned-packages`. Most users will not need or want to do this.
;;(add-to-list 'package-archives '("melpa-stable" . "https://stable.melpa.org/packages/") t)
(package-initialize)

(use-package rust-mode
  :init
  (setq rust-mode-treesitter-derive t))

Upon opening a rust buffer, the Warning buffer shows

Warning (treesit): Cannot activate tree-sitter, because language grammar for rust is unavailable (version-mismatch): 15

I can confirm that the language object is present at ~/.emacs.d/tree-sitter

I also cannot make it work by setting the variable to t, but I managed to make it work with the following code. You can take it as a reference

(defun my-setup/rust-ts-mode ()
  ;; Can work without setting `rust-mode-treesitter-derive` to t
  ;;,add it here just to make sure.
  (setq rust-mode-treesitter-derive t)
  ;; Remove the original cons cell for rust
  (setq auto-mode-alist (delete '("\\.rs\\'" . rust-mode) auto-mode-alist))
  ;; Use `rust-ts-mode` instead of `rust-mode` for .rs files.
  (add-to-list 'auto-mode-alist '("\\.rs\\'" . rust-ts-mode))
  )
(my-setup/rust-ts-mode)

;; If you use eglot, don't forget to start eglot when in rust-ts-mode with the following code
(defun my/eglot-in-rust-mode-hook ()
  (eglot-ensure)
  )
(add-hook 'rust-ts-mode-hook 'my/eglot-in-rust-mode-hook)
