I'm writting a student book and i use the tasks package.

The pdf file work correctly with Sumatrapdf or firefoxplugin but dont work with Adobe Acrobat Reader DC (version 2020.006.20042)

here is a mimimal exemple :

\documentclass{article}
\usepackage{hyperref}

\begin{document}

\tableofcontents

\newpage

\section{One section}

Some text

\end{document}


Does anyone understand what's going on ?

I use Miktex 2.9.7364 and GPL Ghostscript 9.27 on windows 8.

The adobe reader is right here: There is a syntax error in the pdf. The tasks package defines a counter representation for hyperref which contains the closing ), and on the dvips route this is not correctly escaped (such a parenthese is a special char in a pdf).

You can get around this like this:

\documentclass{article}
\usepackage{hyperref}
\ExplSyntaxOn
\ExplSyntaxOff
\begin{document}

\tableofcontents

\newpage

\section{One section}

Some text
