What is the value of user-emacs-directory in your Emacs sessions?

Also, please show the full contents of the ~/.emacs.d/tree-sitter

To debug this, I'd recommend stepping with a debugger into the
function treesit_load_language, and trying to figure out why it fails
to find the shared libraries you installed.
