bug#57112: 29.0.50; Observing Emacs crashes when switching to console and back to X

[Jean Louis <bugs@gnu.support>]

Crashes I have observed during the time when I switch from X to console
by using C-M-Fx key, and then switching back. During that time when
computer was in console, and it also went to sleep in memory as well,
something happens and Emacs crashes.

It is perfectly reproducible.

1. Open "emacs -Q". Press Ctrl-Alt-F2 if X is on console #1, to switch
   to console #2

2. Switch back to console #1 or the console number where the X is
   located.

3. Then I observe that I see Emacs windows just short time and they are
crashing.
