I adapt the answer in Resuming a list to beamer:
\documentclass{beamer}
\usepackage{enumitem}
\begin{document}
\begin{frame}
\begin{enumerate}
\item One
\item Two
\end{enumerate}
Some text
\end{frame}
\begin{frame}
\begin{enumerate}[resume]
\item Three
\end{enumerate}
\end{frame}
\end{document}
Compilation produces an error (while there is no error with document class article):
! TeX capacity exceeded, sorry [grouping levels=255].
\labelenumi ->{
\labelenumi }
l.11 \end{frame}
What is wrong?
enumiteminbeameris hard; see for example the discussions in this question or this one. If your goal is only to resume the enumeration, I think the simplest solution is to avoid usingenumitemand to use another counter instead, as explained in this answer. – Vincent Oct 23 '21 at 19:07
