The debuginfo doesn’t exist because there is no such Fedora build. The current version of gdk-pixbuf2 in F40 is 2.42.10-8.fc40. (See https://src.fedoraproject.org/rpms/gdk-pixbuf2.) Where did you get gdk-pixbuf2-2.42.11-1.fc40?
I am not talking about the debuginfo, but about the gdk-pixbuf2 package itself. Installing gdk-pixbuf2 on a Fedora 40 machine today installs version 2.42.10-8.fc40. Yet somehow you have version 2.42.11-1.fc40 installed. That version did not come from Fedora. Where did you get it? If you don’t know, run rpm -qi gdk-pixbuf2 and paste the output here.
@jjames, rpm -qi gdk-pixbuf2 outputs the undermentioned:

It must have come as a dependency, since I didn’t know of it until now. To my knowledge, I’ve not installed any RPMs from outside the aforelisted repositories, although some of those are evidently non-Fedora (albeit all much-used and organisation-official).
@barryascott, I presume PackageKit must have done that, since I’ve only ever updated via Discover (due to its offline update support). It’s rather worrying that this was ever able to occur.
Do you know how to ascertain how this occurred?

@barryascott, thanks. @vekruse, it seems to work when I request more detail (although I’m uncertain what I should see, since I’ve not used the command before now):

Any coredump / crash data collected before you downgraded gdk-pixbuf2 will no longer be valid, as it will contain addresses in a different version of that library. That may be why you’re seeing all those #14 0x00007f1d533ff220 in ??? ()-type frames.
And if you haven’t restarted your session since the downgrade, you may have processes running that are still using the wrong version of gdk-pixbuf2 because they already had it loaded.
(IOW, “When in doubt, reboot.” Or at least log out and log back in again.)
