I have modified `\AtBeginSection` (with this [answer](https://topanswers.xyz/tex?q=7237#a6915)) with moloch theme but now I get this error when printing the glossary and/or bibliographic references:
```
47: Extra }, or forgotten \endgroup. \end{frame}
47: Extra }, or forgotten \endgroup. \end{frame}
47: \begin{beamer@framepauses} on input line 47 ended by \end{beamer@frameslide}. \end{frame}
50: Missing number, treated as zero. \frametitle
50: Illegal unit of measure (pt inserted). \frametitle
51: Extra }, or forgotten \endgroup. \printbibliography[heading=bibnumbered]
52: Extra }, or forgotten \endgroup. \end{frame}
54: \begin{frame} on input line 49 ended by \end{document}. \end{document}
54: You can't use `\end' in internal vertical mode. \end{document}
54: \begin{frame} on input line 49 ended by \end{document}. \end{document}
: Emergency stop.
: File `q.out' has changed.
```
Here a M(non)WE:
```
\documentclass{beamer}

\usepackage[numberedsection]{glossaries-extra}

\newglossaryentry{woodlouse}
{

}
\usepackage[backend=biber]{biblatex}

\begin{document}
\begin{frame}
\frametitle{}

\printnoidxglossary

\frametitle{Bib}

```
Is there any workarround?

### For the bibliography part of the problem:
- missing `,` after the date in the bib file
- beamer does not like it at all if frames are nested. Unfortunately using `\printbibliography[heading=bibnumbered]` will mean that biblatex starts a new section right there in the middle of the frame. This new section will then try to insert the frame of the section page even tough it already is inside a frame. You can avoid the problem by using `heading=none` and add a new section manually before the bibliography frame.
### For the glossaries part:
There is probably an option to switch off starting a new section at the start of the glossary, but I don't know it. The closes I could get with using package options is `\usepackage[numberedsection=false,section=subsubsection,toc=false]{glossaries-extra}`. This will still start a subsubsection instead of a section and thus allow the document to compile. It will also disable adding an entry to the toc which resulted in a malformed entry because glossaries tried to include the page number, which is normally not shown in a beamer toc.
However I'd prefer to not using sectioning commands like `\subsubsection` within a frame. A brute force approach which disables the glossary section:
```
\documentclass{beamer}
\usetheme{moloch}
\usepackage{glossaries-extra}
\makenoidxglossaries
\makeatletter
\renewcommand*{\@p@glossarysection}[2]{}
\makeatother
