Emacs built with support for tree-sitter. To use it, you must set
treesit-extra-load-path.
(setq treesit-extra-load-path '("~/.guix-home/profile/lib")) or
(setq treesit-extra-load-path '("~/.guix-profile/lib"))
It depends on how you install it.

@fd9a its documentation says that tree-sitter will look eventually in the system default locations for dynamic libraries, is not this enough?
