Errors using enumitem package in Beamer.
05 May 2022I had this problem with beamer recently: I was using \begin{enumerate}, and I got this error:
TeX capacity exceeded, sorry [grouping levels=255]. \end{frame}
The problem was that I was using the enumitem package, which I really like. But anyway, there’s a bug somewhere:
SO post 1, SO post 2.
For me, I removed the \usepackage{enumitem} and everything compiled.
