Weird crash in terminal emacs when invoking shell command with "& disown"

[nasseralkmim]

This crash occurs in terminal emacs, when invoking a shell command with "& disown" to open a pdf file for example.

To reproduce:

1. emacs -Q -nw
2. add embark source code to the load-path (add-to-list 'load-path "/home/user/.emacs.d/elpaca/repos/embark/")
3. (require 'embark)
4. (bind-keys ("C-z" . embark-act))
5. "C-x f" look for a pdf file, then "C-z" "!" open the pdf reader with the shell command: "okular pdffile.pdf & disown"
6. It opens the pdf, now go to emacs again and press "C-g" (keyboard-quit). Emacs crashes.

Not sure how to debug this.

It only happens in terminal emacs.

If I act directly on a file path, it works with no problems, I can open the pdf in a "disown" process and go back to work in emacs.
Only when I act in the minibuffer (after find-file for instance) the problem happens.

I'm running emacs 31.0.50 with native-compilation enabled.
