Does not compile with recent distributions

[kemikkafa]

The issue seems to be due to a lack of maintenance of pdfx package.

Tested on Miktex 21.7 and TexLive 2021

Is it possible to replace pdfx package dependency?

pdfx is really an important package, so hopefully this situation will be fixed soon :-(

In the meantime,

Workaround 1:
Compile with pdflatex-dev instead of pdflatex, because -dev hasn't yet the fix for latex3/latex2e#605. It will still break later when -dev gets the fix too.

Workaround 2:
Add a fixpdfx.sty file with code here: https://tex.stackexchange.com/a/606007
And then write \RequirePackage{fixpdfx} before \documentclass[...]{altacv}
(but this reverses a bugfix for a different issue latex3/latex2e#605)

Thank you for the solutions. I have installed texlive 2020 just to be able to use the class. But that's worth the effort. Thanks for this (yet another) beautiful cv class.
