I confirm Dalyoung's problem with \columnsets on Mac OSX with current lmtx.

The following MnWE worked on July 2021 versions of lmtx, but does not work
with December versions (gives Fatal Error 11)

\definecolumnset[example][n=2]
  \starttext
     \startcolumnset[example]
       \dorecurse{20}{\input bryson}
     \stopcolumnset
  \stoptext

mtx-context     | fatal error: return code: 11


HTH,
