Looking for \endgroup, it can be found in the pstex images under img/tex directory and also in xcomment.tex.

I checked that the xcomment files (.sty, .tex) bundled in the repo match the latest versions on https://www.ctan.org/tex-archive/macros/generic/xcomment

I minimized common.tex to bare minimum and the problem is still there. Using a trivial document this seems like a problem in TeX Live itself: https://tex.stackexchange.com/questions/618066/extra-endgroup-with-trivial-document-using-tex-live-2021

Building with pdfTeX, Version 3.14159265-2.6-1.40.20 (TeX Live 2019/Debian) (preloaded format=pdflatex) works fine.
