I think that means that you're not using a Gtk Emacs, because you should
have gotten something like:

In GNU Emacs 25.2.1 (x86_64-pc-linux-gnu, GTK+ Version 3.24.33)
 of 2022-08-27 built on joga
Windowing system distributor 'The X.Org Foundation', version 11.0.12101003
System Description:     Ubuntu 22.04 LTS

if you did use a Gtk build.  So the crashes you're seeing is probably
not due to the known Gtk limitations.

Emacs 25.2 is very old, though.  Would it be possible for you to upgrade
to something newer (for instance 28.1) and see whether the problem is
still present there?
