Do you have the XPM library installed and available to Emacs?

Your build details indicate that Emacs was configured to be built with
XPM:

> Configured using:
>  'configure --with-pgtk --prefix=/usr --sysconfdir=/etc
>  --sbindir=/usr/bin --bindir=/usr/bin --mandir=/usr/share/man
>  --infodir=/usr/share/info --localstatedir=/var
>  --host=x86_64-unknown-linux-musl --build=x86_64-unknown-linux-musl
>  '--libdir=${exec_prefix}/lib64' --with-file-notification=inotify
>  --with-modules --with-jpeg --with-tiff --with-gif --with-png
>  --with-webp --with-xpm --with-rsvg --without-imagemagick --with-xml2
               ^^^^^^^^^^
>  --with-gnutls --with-sound --with-m17n-flt --with-json --with-harfbuzz
>  --with-cairo --with-libgmp --with-sqlite3 --with-tree-sitter
>  --with-native-compilation=aot 'CFLAGS=-fno-PIE -mtune=generic -O2 -pipe
>  -g -ffile-prefix-map=/builddir/emacs-29.4=.' 'CPPFLAGS= '
>  'LDFLAGS=-no-pie -Wl,--as-needed ''

But the features actually available to Emacs don't include XPM:

> Configured features:
> ACL CAIRO DBUS FREETYPE GIF GLIB GMP GNUTLS GSETTINGS HARFBUZZ JPEG JSON
> LCMS2 LIBOTF LIBXML2 MODULES NATIVE_COMP NOTIFY INOTIFY PDUMPER PGTK PNG
> RSVG SECCOMP SOUND SQLITE3 THREADS TIFF TOOLKIT_SCROLL_BARS TREE_SITTER
> WEBP XIM GTK3 ZLIB

So I wonder how this happened.

Did you build Emacs yourself, or was it installed from some distro?
