Why does the unpacked electron exe app create xlsx for me, but the portable exe does not create it, although it also works?

Question

JavaScript

I wrote an application that parses different sites in the main process (main) without using executeJavascript (I connect it as a regular module). main sends messages to html about which site is loaded and the final one. The application itself works 100% if you run the portable version or the one that is unpacked inside the win-unpacked folder. the unpacked one creates an xlsx file outside the folder, but the portable one does not. why can that be? library for generating excel - exseljs. last line
workbook.xlsx.writeFile(../${title}.xlsx);
