tcolorboxes in beamer

Question

This code isn´t working. Can anyone please tell me, why this tcolorbox isn´t working? (In documentclass "article" it is working, but not in "beamer").

\documentclass[aspectratio=169, xcolor=dvipsnames, 10pt]{beamer}

\usetheme[subsectionpage=progressbar]{metropolis}
\usepackage{tcolorbox}

\begin{document}

\begin{frame}
\begin{tcolorbox}[
    sharp corners, breakable, frame hidden, enhanced, boxrule=0pt,
    borderline west={3pt}{0pt}{red},
    segmentation style={red, line width=1.5pt, solid},
    colback=red!10,
    ]
    Test, jetzt bin ich gespannt
\end{tcolorbox}
\end{frame}


\end{document}

Answer 1

• For your definition of \tcolorbox style you need to load tcolorbox package with option many or breakable and skins.
• After adding many option and compose your code fragments into MWE (Minimal Working Example, see it below) works fine. So it is unclear what is actually your problem.
• Off-topic, I don't see any sense that you require that \tcolorbox should be breakable.

Test MWE:

\documentclass[aspectratio=169, xcolor=dvipsnames, 10pt]{beamer}
\usetheme[subsectionpage=progressbar]{metropolis}
\usepackage[many]{tcolorbox}
\usepackage{lipsum}

\begin{document}
\begin{frame}
\frametitle{Use of the \texttt{tcolorbox}}
    \begin{tcolorbox}[
        sharp corners, %breakable, 
        frame hidden, enhanced, boxrule=0pt,
        borderline west={3pt}{0pt}{red},
        segmentation style={red, line width=1.5pt, solid},
        colback=red!10,
        ]
    \lipsum[66]
    \end{tcolorbox}
\end{frame}
\end{document}
