I think I pinpointed the problem.
I was able to reproduce the bug with a minimal init configuration that only
loads the vterm package.

I'll attach the init file here, hope this helps!

;; This seems to be the minimum init file that I can use to replicate the bug discussed in "bug#62831: 29.0.90; Emacs-pretest-29.0.90 aarch64 on macOS crashes when receiving a three-finger tap."
;;
;; Running this init file with:
;; /Applications/Emacs29.app/Contents/MacOS/Emacs -Q --load="~/.emacs.d/bug-only-init.el"
;; seems to cause a crash in connection with the macOS three-finger-tap functionality, that can be enabled in:
;; System Preferences -> Trackpad -> Point & Click -> Look up & data detectors, Tap with three fingers.
;;
;; Version of Emacs I used to replicate the bug:
;;
;; GNU Emacs 29.0.90 (build 1, aarch64-apple-darwin21.6.0, NS appkit-2113.60 Version 12.6.1 (Build 21G217)) of 2023-04-11
