I am trying to compile a simple latex file.

documentclass[12pt]{article}
usepackage[a4paper,margin=2.05cm]{geometry}
usepackage{graphicx}
% usepackage{grfext}

graphicspath{{./figures/}}
% graphicspath{{./}{./figures/}}

% DeclareGraphicsExtensions{.pdf,.eps}
% AtBeginDocument{%
%   PrependGraphicsExtensions*{
%     .mps,.MPS,.pdf,.PDF,.eps,.EPS,.ps,.PS,
%     .png,.PNG,.jpg,.jpeg,.JPG,.JPEG,
%   }%
%   %PrintGraphicsExtensions % see .log file
% }

begin{document}
includegraphics[width=0.45textwidth]{quadrant}
end{document}

Earlier I think I didn’t need to add the current folder to the graphicspath. But now it doesn’t seem to work. How do I add the current folder to graphicspath, since graphicspath{{./}{./figures/}} doesn’t seem to work (unless I add the extension .pdf in the tex file, i.e. quadrant.pdf, which I don’t want to)?

My current pdflatex version (from the log file) is as follows:

This is pdfTeX, Version 3.141592653-2.6-1.40.22 (TeX Live 2022/dev/Debian) (preloaded
