[Tex/LaTex] “! LaTeX Error: Too many symbol fonts declared.” error!

Question

I am trying to use stix font in beamer class:

\documentclass[standalone]{beamer}
\usepackage{tkz-euclide,tikz,stix}

\begin{document}
\begin{frame}
\begin{tikzpicture}
\coordinate [label =above:$C$](c) at (0,0);
\draw (c) circle (2cm);
\end{tikzpicture}
\end{frame}
\end{document}

and I am getting that error "! LaTeX Error: Too many symbol fonts declared." error!", Any ideas what is the problem?

I used the same source code inside standalone class and it worked well! I think the problem is with beamer..

and I've tried that solution Times new roman and bm in beamer but it apparently did not work, I am no longer get the error message but the text font doesn't change!

Answer 1

Try with \usefonttheme{professionalfonts}, this disables all the things beamer normally does concerning fonts.

\documentclass[standalone]{beamer}

\usefonttheme{professionalfonts}

\usepackage{stix}
\usepackage{tkz-euclide,tikz}


\begin{document}
\begin{frame}
\begin{tikzpicture}
\coordinate [label=above:$C$](c) at (0,0);
\draw (c) circle (2cm);
\end{tikzpicture}
\end{frame}
\end{document}
