[Tex/LaTex] ! Undefined control sequence. \reserved@b ->C:\Users l.69 \end{frame}


I'm running \documentclass{beamer} on pdfstudio in Windows 10. When I compile appears an error in many frames, and I can't find out where is the error, the error line 69 refers to:

\section{Descripción Tema y Motivación}
\frametitle{Descripción Tema y Motivación}

and the error is:

! Undefined control sequence.
\reserved@b ->C:\Users 
                       \eric .sanchez\Desktop \IFOP _investigador\ppt \figur...
l.69 \end{frame}

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

Thanks in advance for any help, Eric

You seem to have a \graphicspath command that uses backslashes in its argument. Replace them by slashes (e.g C:/Users).

And if possible avoid absolute pathes, normally they are not a good idea.
