Hi, I am using the latest emacs-30 https://github.com/emacs-mirror/emacs/commit/c6077015894dd89c5aa3811bf55d3124394874d0  The min configuration is as follows: (add-to-list 'treesit-extra-load-path (expand-file-name "tree-sitter/" user-emacs-directory)) (add-to-list 'load-path "~/.emacs.d/site-lisp/clojure-ts-mode”) (require 'clojure-ts-mode) ;; debug (setq debug-on-quit t) and I only use clojure-ts-mode package cd ~/.emacs.d/site-lisp git clone https://github.com/clojure-emacs/clojure-ts-mode.git Then, after opening Emacs, Open the elong.clj file, After moving to line 52, delete all the characters following :error-code, then quickly press the spacebar twice. At this point, it freezes. ------------ Sincerely, Haiyuan Zhang, Vinurs BinaryBrain LLC
