Also, just to add in, the previous version: Emacs 27.2 is working fine on the system and no Abort dialog is shown.I just installed it and checked.

  Yes, now that I think of it, it doesn't show Abort dialog while displaying the scratch buffer.
But if `-q` is used, it does, like if I'd have normally opened it.   On Sunday, 1 May, 2022, 08:02:46 pm IST, Eli Zaretskii <eliz@gnu.org> wrote:

So in the first two cases, Emacs displays *scratch* (for -Q) or the
splash screen (for -q), and _then_ shows the Abort dialog?
