r/LaTeX

How would I go about trying to recreate this

For some reason Polish breaks biblatex. I have simple test article

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}

\usepackage[style=apa, sorting=none]{biblatex}
\addbibresource{sample.bib}

\begin{document}

	This should always work (\cite{einstein})

\printbibliography

\end{document}

This works and everything is fine, but when I change \usepackage[english]{babel} to polish it doesn't compile and I get errors

Undefined control sequence. This should always work (\cite{einstein})
Undefined control sequence.

I tried with German, Spanish and even Russian and it worked but Polish doesn't, why? How to fix? I use TeXstudio

Hi,

I have never been really keen on using those, but things might have change!
