[Message part 1 (text/plain, inline)]

It may be worth establishing a baseline. Try the following and see if you
get a segfault:

  1. Download and install
https://mirrors.ibiblio.org/gnu/emacs/windows/emacs-29/emacs-29.4-installer.exe
  2. After installation, use Windows Explorer/Start Button to run Emacs (do
not run via MSYS terminal).
  3. M-x customize-group, and then choose any group to get to the "Easy
Customization" screen.
  4. Place cursor in the search field:

     For help using this buffer, see [Easy Customization] in the [Emacs
manual].

     [                                      ]  [ Search ]
      ^
      +---------- place within search area

  5. Type any group name to customize. I typed "default" for the group and
pressed enter.
  6. The segfault should occur right after pressing enter.

If this doesn't segfault for you, then it may be something specifically
related to running Emacs within a Windows 11 VM via Parallels on an M1
MacBook Pro (ARM64).
