Emacs 29 (and nightly) comes with a builtin support for tree-sitter.
Looking at emacsformacosx, all nightly builds since 2023/3/10 have
tree-sitter builtin. To try that out, you can follow this guide:

https://archive.casouri.cc/note/2023/tree-sitter-in-emacs-29/index.html

A easy way to distinguish between the third-party package and the
builtin support is to look at the prefix, tree-sitter-xxx is the
third-party one, treesit-xxx is the builtin one.

Nice. thanks for the link.  After setting up the built-in treesitter it does not crash. To clarify, the init file I am using for this case is:

(add-to-list 'major-mode-remap-alist '(c-mode . c-ts-mode))
(add-to-list 'treesit-language-source-alist
         '(c "https://github.com/tree-sitter/tree-sitter-c.git"))

And the tree-sitter command line:

$ type -a tree-sitter
tree-sitter is /opt/homebrew/bin/tree-sitter
$ tree-sitter --version
tree-sitter 0.20.8

It does still fail with the external treesitter package. I tried on both v28 where it is required as well as v29.

I spoke too soon. It does indeed crash with the builtin tree-sitter library. I was using my desktop keyboard shared using barrier.  When I use the laptop keyboard, the crash still happens.
