From latest git sources, starting (IIRC) 2023-12-01:

⛔ Warning (initialization): An error occurred while loading
‘/home/acs/.config/emacs/init.el’:

error: Invalid face box, :line-width, 2, :color, #002732, :style,
unspecified

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the ‘--debug-init’ option to view a complete error backtrace.

This runs without error in earlier versions.  Please let me know if you'd
like more detail.

HTH,
