Can't include SVG image in LuaLaTex (MikTeX)

Question

I have problems including an .svg image into my document (I'm using MikTeX on Windows 10). I found relevant Q&As here and I think I know which steps I need to take in order to import svg images:

• I have inkscape in PATH
• I added the --shell-escape or --write18 option (tried both)

Those are my settings:

I copy and pasted the example from this answer

\documentclass{article}
\usepackage{svg}
\usepackage{amsmath}
\begin{document}
\begin{figure}[htbp]
  \centering
  \includesvg{image}
  \caption{svg image}
\end{figure}
\end{document}

but I still get this error:

? 

I have an image.svg file in the same folder like the tex document. I need this to work with LuaLaTeX, but I also tried pdfLaTeX, getting the same error... The compiler complains that I didn't enable 'shell escape' (or 'write18'), so what am I doing wrong? Did I violate the syntax in the settings?
