TexLive 2019 and 2018 issue

[Spyros]

Good evening.
I recently installed Texlive 2018 in my pc in order to move from Miktex to
Texlive. The moment that the installation was finished I tried to compile
the following MWE



\documentclass[10pt,a4paper]{article}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}
\begin{document}
sample
\end{document}



but no matter what I try to get it working I get this error

I got the same error with Texlive 2019 thats why I tried to install an
older version. Also I want to mention that the update isn't working and
that I have MikTex installed as well so I can get my work done until
Texlive is working. Any thoughts?

I read that these kind of errors are caused by Perl issues. I have a full
installation of Strawberry Perl in my computer and still this does got fix
the error. I have also added TexLive variable to the PATH, placed above
MikTex.

In my other computer I have the same Texlive and Texstudio installation
without the need to install Perl as everything works.


Thank you.
