Latest TeX Live update breaks PDF build with pdfx package

[Stephan Lukasczyk]

Hi all,

I am pretty sure this is the wrong mailing list, but since many core
developers are here and I do not really know where to put this, let me
report a bug I encountered after pulling the latest updates for TeX Live
2024 (state 3 June 2024):

Compiling the following MWE with lualatex:
> \documentclass{article}
> \usepackage{colorprofiles}
> \usepackage[a-2b,mathxmp]{pdfx}
> %\usepackage{hyperref}
> \begin{document}
> Hello world.
> \end{document}

yields:

>$ lualatex test

If I comment out the loading of `pdfx` and instead load `hyperref` everything 
works as expected.  It also used to work until yesterday, thus I believe
this might be related to probably a kernel update of LaTeX?

Any help is appreciated.

Best,
   Stephan
