Can't compile after reinstalling

Question

I had some issues regarding some python code highlighting packages for the minted package. I ended up trying to revert all the changes since I could not make it work. Apparently I might have broken the compiler afaik, since I was stuck with the message Error: Could not start the command: Compile & View

Even after restoring default command pdflatex -synctex=1 -interaction=nonstopmode %.tex and making sure it is the default compiler PdfLaTeX and cleaning aux files - the error still persisted.

I ended up purging TeXstudio, texlive and tex-common and reinstalling them. Yet the error still persists.

even trying to compile

\documentclass[a4paper,10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\begin{document}    
    \section{Some section}
    something
\part{title}
\end{document}

results in an error.

When compiling with TexStudio I get the following error: Compile results in Error: Could not start the command: PdfLaTeX

out of sheer frustration i deleted both python and pip with no hopes with nothing as the expected result.

Edit

It should be noted that through some comments I think we can narrow it down to being a TexStudio configuration, since it does compile as expected through the terminal.

Welcome on TeX SE !

I think that your code is not giving any output because you're not adding content in document. When you start working on a document in LaTeX, you have two different parts in your file :

\documentclass[a4paper,10pt]{article}

% Preamble
% This is where you add packages and you set your layout

\begin{document}

% Content
% This is what will show up in your PDF

\end{document}

Edit: Concerning TeXStudio, I think this answer and this answer can help you. If you need to know where is pdflatex in your computer, you can use the following command in Command Prompt (if you're using Windows) :
