upstream report: https://gitlab.gnome.org/GNOME/libxml2/-/issues/526

this might be a similar issue as:
https://gitlab.gnome.org/GNOME/libxml2/-/issues/433

the likely cause, however, is symbol visibility. from the changelog:

 This release finally fixes symbol visibility on UNIX systems. Internal sym=
bols
 will now be hidden. While these symbols were never declared in public  hea=
ders,
 it was still possible to declare them manually. Now this won't work.

 All symbol information has been removed from the ELF version script to fix
 link errors with --no-undefined-version. The version nodes are kept so it
 should still be possible to run binaries linked against older versions.

distributors should most likely rebuild everything against this version,
or find a way to toggle to the old version, to ensure ABI compatibility.
