[Tex/LaTex] File l3backend-pdftex.def Not Found, even after installing l3backend

errorspackages

I've seen the previous threads on this error such as this thread and this and carried out the instructions here.

So that being said, I've installed l3backend through MikTex Console and I still receive this error. Here's a screenshot of my MikTeX console. Screenshot of MikTex Console

I'm getting the error on the simplest possible examples. Here is what the setup wizard puts out — it gives me an error.

\documentclass[12pt,a4paper]{report}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\begin{document}
This... is a test...
\end{document}

Screenshot of TexMaker follows. I've reinstalled MikTex, reinstalled the l3backend package and restarted my computer numerous times. Not sure what to do next. Any help is appreciated. Thanks.

This answer is not going to solve the problem with MiKTeX but I found a way to get around it and I'm putting this out there for someone who is on the same boat as I was. I scraped the internet to solve the problem with MiKTeX and found NO solution that worked for me. I ended up giving up on MikTeX (possibly forever), uninstalled it completely and had a fresh install of TeX Live. My TeX stuff work like a charm now... just saying!
