I have created vertically split circle and it works standalone but it stop when I add this code to my university template. Here is standalone code:

\documentclass[tikz]{standalone}
% BEGIN section 1 
\usepackage{tikz}
\usetikzlibrary{calc, positioning,fit}
% END section 1
\begin{document}
% BEGIN section 2
\begin{tikzpicture}[scale=1]
\tikzset{
    pics/circle vertically split/.style 2 args = {
       code = {
         \pgfmathsetmacro{\widthOne}{width("#1")+4pt}
         \pgfmathsetmacro{\widthTwo}{width("#2")+4pt}

         \node[text=green](-this_is_currcent_center){+};
         \node[xshift=-\widthOne/2] (-left) {#1};
         \node[xshift=\widthTwo/2] (-right) {#2};
         \node[fit=(-left)(-right),draw,circle,text=red](-shape) {+};
         \node(-splitline) at ($ (-left.east)!.5!(-right.west) $) {};
         \draw (-shape.north east -| -splitline.center) -- (-shape.south east -| -splitline.center);
       }
    }
}
% this doesn't center correctly but it's not part of this question
\pic[inner sep = 1pt, align=left] (A) {circle vertically split={$Aaaaaa$}{$B$}};
\pic[inner sep = 1pt, align=left, right = of A-shape] (B) {circle vertically split={A}{$Bbbbb$}};
\end{tikzpicture}
% END section 2
\end{document}

Standalone code produce: result of standalone code

Error after adding to university template:

! Package PGF Math Error: Unknown function `Aaaaaa' (in 'width(""Aaaaaa"")+4pt' ).

How to reproduce error

For anyone who want to help me I created a quick way to repoduce error in 30s:

  1. Clone repository (this is fork of template) --git clone https://github.com/xoac/aghdpl-imir.git
  2. Checkout to branch split-circle -- git checkout split-circle
  3. Compile with command latexmk -outdir=build -pdf praca.tex

Additional information:

Check difference between raw template and after my changes git diff master split-circle

pdflatex --version:

How can I find why it stopped compiling after adding my code?

I create my vertically split circle mixed this two solutions: 1. https://tex.stackexchange.com/a/528851/192768 2. https://tex.stackexchange.com/a/186506/192768

The problem is probably that your format is used with 

\usepackage[english, polish]{babel}

which transforms the meaning of some special char (technically it makes chars active), in this case probably the quote " which I suppose it is used to add some accent around... (I do not know Polish, so I don't know the details).

If you use utf8 to input special chars, you can try to disable babel shorthands with

 \usepackage[english, polish, shorthands=off]{babel}

or you can try loading the TikZ library 

   \usetikzlibrary{babel}

I think that both approaches work in your example.

Problem with babel and tikz using \draw is very similar to this, I suspect.
