I use BibLaTeX to produce my professional CV, and recently moved into a new computer, installing all the latest apps (MiKTeX, BibLaTeX). When I try to compile my CV -- unmodified from another computer where this setup works flawlessly -- the latest version of BibLaTeX seems to choke on the refsection (as best I can tell), with the following error:
! Missing \endcsname inserted.
\relax
l.89 \end
{refsection}
?
My other computer, with the 2020 version of BibLaTeX, works just fine on this same .tex file. I am guessing it is an issue with BibLaTeX 3.19??
It can't be that general or we would have had thousands of complaints - can you post a MWE to tex.stackexchange.com? This is usually some third-party package interaction issue.
