I don't see how this could be related to tree-sitter at all.  There's
nothing tree-sitter related in the backtrace; the crash happens when
Emacs simply waits for input in read_char.

It's some macOS specific issue with the way we integrate into the NS
window-system, not related to tree-sitter, at least not on our code
level.  It could be some incompatibility between the tree-sitter
binary used and the version of macOS or the hardware used to run
Emacs, or something like that.
