The following code now fails. It works as expected under 2023.05.05 as 
found in the texlive.net runner.

    \defineparagraphs[TwoCols][n=2]
    \setupparagraphs[TwoCols][2][\width=.5\textwidth]
    \starttext

    \input knuth \par

    \startTwoCols
    \input knuth \par
    \nextTwoCols
    \input knuth \par
    \stopTwoCols

    \input knuth \par

    \stoptext
