It fails for me in texlive 2023. 

I don't know who changed what here, but it looks like a catcode
problem. context loads tikz files in m-tikz.mkxl with
\tikzinputfiles, and that calls \setcatcodetable\texcatcodes. After
that ~ has catcode 12 and that breaks the \let~\pdfmath@char@quote
in the pgfmathparser.code.tex file 

\begingroup
  \lccode`\~=`\"
  \lowercase{\endgroup
    \def\pgfmath@catcodes{%
      \catcode`\==12 %
      \catcode`\,=12 %
      \catcode`\|=12 %
      \catcode`\&=12 %
      \let~\pgfmath@char@quote
    }}%
