How to make the references appear in order in LaTeX?

Question

I have a well-known problem in LaTeX, even though my case seems to be a little bit special. I've tried all the possible solutions suggested at "StackExchange" and elsewhere but I didn't succeed to solve it.

Actually, I am working on a paper and I've typed all the references using the 'biblatex' package. Once I printed them, I found that they are not in order in the text (e.g. what is supposed to be [2] is mentioned as [17], etc.). I've checked some solutions on the net such as replacing \printbibliography with \bibliographystyle{unsrt} followed by \bibliography{} (with the name of the .bib file inside without the extension) among many others, but all of them failed! To understand what I've done, I will attach a part of my .bib file's code.

@misc{NobelFermi,
author = {NobelPrize.org. Nobel Prize Outreach AB 2022},
title = {Enrico Fermi – Biographical},
 %year = {2022},
%note = {Last accessed January 2022},
url = {https://www.nobelprize.org/prizes/physics/1938/fermi/biographical/}
}
\\
 @article{LucaNanni,
title={Fermi’s theory of beta decay: a first attempt at electroweak unification},
author={Luca Nanni},
journal={Advanced Studies in Theoretical Physics},
volume={13},
number={6},
pages={281--293},
year={2019},
publisher={Hikari Ltd},
doi={https://doi.org/10.12988/astp.2019.8939}
}

And in the text, I've used the \cite commands. And below, I attach the preamble of my .tex file...

\documentclass[eqn,10pt]{SelfArx} % Document font size and equations flushed left
\usepackage[english]{babel} % Specify a different language here - english by default
\usepackage[utf8]{inputenc}
\usepackage[document]{ragged2e}
\usepackage[T1]{fontenc}
\usepackage{graphicx}
\usepackage{titlesec}
\usepackage{epigraph}
\usepackage[autostyle]{csquotes}
\usepackage[latin1]{inputenc}
\usepackage{caption}
\usepackage{wrapfig}
\usepackage{color}
\usepackage{multicol}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{mathtools}
\usepackage{amsbsy}
\usepackage{lettrine} %For the enlarged capital letter in the beginning 
\NoAutoSpaceBeforeFDP
\usepackage{mathrsfs} %For the mathematical font style "mathscr"
\usepackage{xcolor}
\usepackage{biblatex} %For citation
\usepackage{url} %for the URL of websites  
\addbibresource{Ref.bib} %To add Ref.bib file

And at the end of the document, I put this command...

\printbibliography

And the generated document looks like this...(The colored numbers in red are the "logical" order of references which I wrote myself to verify their ordering in the text).

The result seems chaotic as you can see.

The comment thread has gotten entirely too long … I am posting an example of what I think you might be wanting, even though it's impossible to tell without a proper MWE:

\documentclass{article}

% Only for debugging. If you provide your own .bib file just
% remove the filecontents part and don't forget to change 
% \addbibresource{mwe.bib} below.

\begin{filecontents*}[overwrite]{mwe.bib} 

@misc{NobelFermi,
    title        = {Enrico Fermi – Biographical},
    author       = {NobelPrize.org. Nobel Prize Outreach AB 2022},
    year         = 2022,
    url          = {https://www.nobelprize.org/prizes/physics/1938/fermi/biographical/},
    note         = {Last accessed January 2022}
}
@article{LucaNanni,

    journal      = {Advanced Studies in Theoretical Physics},

    volume       = 13,

    doi          = {https://doi.org/10.12988/astp.2019.8939}
}

\end{filecontents*}

\usepackage[english]{babel}

\usepackage[backend=biber,sorting=none,style=numeric-comp]{biblatex}
\addbibresource{mwe.bib}

\begin{document}

Dolor sit amet.\cite{LucaNanni}
Lorem ipsum.\cite{NobelFermi}

\printbibliography

\end{document}

You can, of course, also use your own .bib file, like so:

\documentclass{article}

\usepackage[english]{babel}

\usepackage[sorting=none,style=numeric-comp]{biblatex}
\addbibresource{Ref.bib}

\begin{document}

Dolor sit amet.\cite{LucaNanni}
Lorem ipsum.\cite{NobelFermi}

\printbibliography

\end{document}
