[Tex/LaTex] Biber cannot cite multiple references – ! Undefined control sequence. \blx@tempb

Question

Since I updated MiKTeX I have been having issues when compiling my references.
It works fine If I only cite one reference e.g. \cite{a} but when I want to cite multiple references e.g. \cite{a, b, c} I get the following error:

! Undefined control sequence.
<argument> \blx@tempb 

l.243 ...\cite{Verre2012a, Verre2012b, Verre2011}.

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.

I have tried deleting all the generated files -> does not work

I have tried reinstalling MiKTeX, Texmaker -> does not work

I have tried looking for a solution only -> nothing related showed up

Here's is the settings I use

\usepackage[backend=biber ,natbib=true ,style=ieee,defernumbers=false]{biblatex}
\addbibresource{Chapters/Chapter_introduction/chap_intro.bib}
\include{Chapters/Chapter_introduction/chap_intro}

Here is a snippet of the .bib file

@article{Verre2012a,
author = {Verre, R. and Fleischer, K. and Ualibek, O. and Shvets, I. V.},
journal = {Applied Physics Letters},
number = {3},
title = {{Self-assembled broadband plasmonic nanoparticle arrays for sensing applications}},
volume = {100},
year = {2012}
}

@article{Verre2012b,
author = {Verre, R and Fleischer, K and McGilp, J F and Fox, D and Behan, G and Zhang, H and Shvets, I V},
journal = {Nanotechnology},
number = {3},
pages = {035606},
title = {{Controlled in situ growth of tunable plasmonic self-assembled nanoparticle arrays}},
volume = {23},
year = {2012}
}

@article{Verre2012,
author = {Verre, R. and Fleischer, K. and Ualibek, O. and Shvets, I. V.},
journal = {Applied Physics Letters},
number = {3},
pages = {031102},
title = {{Self-assembled broadband plasmonic nanoparticle arrays for sensing applications}},
volume = {100},
year = {2012}
}

Again it worked fine before the update, which was something like MiKTeX 2.9.6600, and the new one is 2.9.6753. I use Texmaker.

I hope this is enough information.

Thanks in advance

EDIT 1

After looking at the comments I tried the example from here.

It works fine with style=numeric-comp but not with style=ieee.

So you might be able to reproduce the error by trying

\documentclass{article}

\usepackage{filecontents}

\begin{filecontents}{bib.bib}
@article {a,
    title = {A title},
    auhtor = {A. Author},
    year = {2000},
}
@article {b,
    title = {B title},
    auhtor = {B. Author},
    year = {2000},
} 
@article {c,
    title = {C title},
    auhtor = {C. Author},
    year = {2000},
} 
@article {d,
    title = {D title},
    auhtor = {D. Author},
    year = {2000},
} 
\end{filecontents}

\usepackage[
backend=biber, 
style=ieee
]{biblatex}

\addglobalbib{bib.bib}

\begin{document}
\newrefsection
\cite{a, b}
\newrefcontext[labelprefix=A.]
\printbibliography

\newrefsection
\cite{c, d}
\newrefcontext[labelprefix=B.]
\printbibliography
\end{document}

EDIT 2

I am not sure if this is the correct place to show a more precise example, but I have been testing and here is a full example which does not compile for me

The files are in the correct folder and what happens is if I comment either includes e.g. %\include{Chapters/Chapter_tech_exp/chap_tech_exp}. It works as expected.

If I comment the multiple citations e.g. multiple citations %\cite{Harden1959,Wagner2000, Aspnes1988}. in the second file, it works, but not if I comment it only in the first file.

And finally if I remove the style i.e. \usepackage[backend=biber, defernumbers=false]{biblatex} It works as well.

I am clueless …

Answer 1

This was about a bug in biblatex that has been resolved in version 3.12. Update your TeX system in case you experience this issue.

The answer below is kept for historical interest.

This MWE reproduces the issue

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[backend=biber, style=numeric-comp, sorting=none, defernumbers=true]{biblatex}

\addbibresource{biblatex-examples.bib}
\usepackage[autostyle=true]{csquotes}

\begin{document}
\begin{refsection}
single citation \cite{sigfridsson}, \cite{nussbaum}.
multiple citations \cite{sigfridsson,nussbaum, worman}. 
\newrefcontext[labelprefix=A]
\printbibliography
\end{refsection}

\begin{refsection}
single citation \cite{sigfridsson}, \cite{nussbaum}.
multiple citations \cite{sigfridsson,nussbaum, worman}. 

\newrefcontext[labelprefix=B]
\printbibliography
\end{refsection}
\end{document}

The problem is related to https://github.com/plk/biblatex/issues/697. In fact it is the same issue just with \begin{refsection}...\end{refsection} instead of \newrefsection.

As a workaround until the problem is fixed, use \newrefsection instead of \begin{refsection}...\end{refsection}. This is not entirely equivalent in all cases, but should hopefully work for you.

\newrefcontext[labelprefix=B]

In the comments you mentioned issues with \newrefcontext, you can try a different workaround, my first suggestion would be

\makeatletter
\protected\def\endrefsection{% 
   \endrefcontext
   \blx@endrefsection 
   \blx@inf@refsec} 
\makeatother

Add this to your preamble after you load biblatex.
