TeXlive 2017 下的任务包出现问题

Question

我昨天更新了 texlive 2017，突然无法使用该tasks软件包。刚刚写\usepackage{tasks}了pdflatex，lualatex然后xelatex卡了几个小时。

\documentclass[11pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{tasks}
\begin{document}
Just a test.
\end{document}

屏幕上的最后几行是：

(/usr/local/texlive/2017/texmf-dist/tex/generic/pgf/utilities/pgfkeysfiltered
.code.tex))))
(/usr/local/texlive/2017/texmf-dist/tex/generic/oberdiek/ltxcmds.sty)
(/usr/local/texlive/2017/texmf-dist/tex/generic/oberdiek/pdftexcmds.sty
(/usr/local/texlive/2017/texmf-dist/tex/generic/oberdiek/infwarerr.sty)
(/usr/local/texlive/2017/texmf-dist/tex/generic/oberdiek/ifluatex.sty)
(/usr/local/texlive/2017/texmf-dist/tex/generic/oberdiek/ifpdf.sty))

CTRL-C 之后：

! Interruption.
\etb@defparser@arg ... #2\noexpand \etb@lst@q@end 
                                                  \noexpand #2&}\long \csdef...
l.147 \DeclareListParser*{\cnltx@map@tokenlist}{}
?

日志文件的结尾是：

Package pdftexcmds Info: LuaTeX not detected.
Package pdftexcmds Info: \pdf@primitive is available.
Package pdftexcmds Info: \pdf@ifprimitive is available.
Package pdftexcmds Info: \pdfdraftmode found.

知道什么地方出了问题吗？
