# Subfile with input - subfile directory auto added path?

I have a LaTeX project that will compile on my computer with MiKTeX, but not on my colleagues with TeX Live. The issue is that when I input the subfile, it appears that my computer adds the subfile's directory to path, but on my colleagues it doesn't, resulting in a TestSubInput.tex not found error. Any ideas as to why this is happening?

The files are organized as follows:

In the main folder

TestMain.tex
/TestFolder/


In the test folder

TestSub.tex
TestSubInput.tex


The contents of the files are:

TestMain.tex, the main file

\documentclass[11pt,a4paper]{scrartcl}
\usepackage{subfiles}
\begin{document}
Main works\\
\subfile{./TestFolder/TestSub.tex}
\end{document}


TestSub.tex, the subfile inserted from main

\documentclass[./../TestMain.tex]{subfiles}
\begin{document}
Sub works\\
\input{TestSubInput}
\end{document}


Note for above, it will compile on both if the input is changed to \input{./TestFolder/TestSubInput}

TestSubInput.tex, the file that is inserted from the subfile

SubInput works
