LaTeX compilation fails for non-native document classes

[Maheshivara]

Hello, and first of all, amazing tool! Thanks for developing and sharing it.

I encountered this issue while trying to open my (still in progress) thesis. I'm not sure whether this is a bug or simply a limitation of the tool, but I wanted to report it, thank you in advance for your attention.

Description

When compiling a LaTeX document that uses a non-standard document class, the compiler fails with an error indicating that the class file cannot be found.

For example, using the memoir class:

\documentclass{memoir}

\begin{document}
This is a test.
\end{document}

produces the following error:

LaTeX Error: File `memoir.cls' not found.

as shown in the image below.

The same behavior occurs when using the abntex2 document class.

Steps to Reproduce

1. Create a LaTeX document using a non-standard document class (e.g., memoir).
2. Compile the document.
3. Observe the compilation failure.

Expected Behavior

The compiler should either:

• Successfully compile documents that use supported CTAN document classes, or
• Clearly indicate that custom/non-standard document classes are not supported.

Actual Behavior

Compilation fails with:

LaTeX Error: File `memoir.cls' not found.

and the document cannot be compiled.
