"nbconvert failed: xelatex not found on PATH"

Try downloading MikTex from this link:
https://miktex.en.lo4d.com/windows#google_vignette

I've no idea about lo4d.com, but where possible I'd always look for a download link on a project's own site, rather than a big download site. For MikTex, that appears to be https://miktex.org/download .

nbconvert --to pdf works by converting to latex first and calling latex. So it does require some variant of latex installed. You can also try --to webpdf or --to qtpdf, which use different ways to create PDFs - but both also use extra, non-Python components.
