\document ->\endgroup ERROR

Question

These two lines:

\documentclass[aps,prl,two column]{revtex4}%
\begin{document}

Produce the following error:

! Extra \endgroup.
\document ->\endgroup 
                      \init@documenthook \set@typesize@hook \normalsize \set...
l.2 \begin{document}
?

the exact error from the errors window is:
8 Extra \endgroup. \document ->\endgroup \init@documenthook \set@typesize@hook \normalsize \set... l.8 \begin{document} — Gal V, Oct 24 '20 at 07:32
Did you check for updates? The problem should be resolved with the newest version of the class — Ulrike Fischer, Oct 24 '20 at 07:52
@campa revtex4 is no longer developed, but it did get a maintenance update a couple of weeks ago precisely to fix this error (so updating will fix the issue). But yes, it's ancient and should not be used. — Phelype Oleinik, Oct 24 '20 at 11:17
@PhelypeOleinik, thanks! What package should be used instead? — Gal V, Oct 25 '20 at 08:53

Use \documentclass[aps,prl,two column]{revtex4-2} instead of \documentclass[aps,prl,two column]{revtex4}.

Even though using revtex4 is not recommended (it's been obsolete for decades now), it was updated to fix this particular issue. – Phelype Oleinik May 09 '22 at 12:52
