Not quite sure if this is a bug per-se, since there are some of the
default configurations concerning fonts, which you have deliberately
disabled.

This is the value of `system-configuration-features' on my build:

--8<---------------cut here---------------start------------->8---
"ACL CAIRO DBUS FREETYPE GIF GLIB GMP GNUTLS GPM GSETTINGS HARFBUZZ JPEG
JSON LCMS2 LIBSYSTEMD LIBXML2 MODULES NATIVE_COMP NOTIFY INOTIFY PDUMPER
PGTK PNG RSVG SECCOMP SOUND SQLITE3 THREADS TIFF TOOLKIT_SCROLL_BARS
TREE_SITTER WEBP XIM GTK3 ZLIB"
--8<---------------cut here---------------end--------------->8---

Someone more qualified may be able to answer which feature(s) exactly
are needed for having fonts work correctly.

What is the value of this variable on a `--without-all' build?  And does
the issue occur on both GUI ("emacs -Q") session and TUI ("emacs -Q
-nw") session?
