How can I show affiliation in title page of bookdown pdf book while using authblk latex package?

Question

I am using bookdown package in R to compile a bookdown::pdf_book. But I am unable to knit it when I use authblk latex package. The strange thing is that I can compile the same thing outside of RStudio, even when I am using authblk latex package. Let me share a minimal example here. Preamble taken from TeXStudio

\documentclass[a4paper,12pt]{book}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{authblk}

\begin{document}

\author[1]{First Author Name}
\author[2]{Second Author Name}
\affil[1]{College1}
\affil[2]{College2}
\title{Simple Book Example}
\date{January 2013}

\frontmatter
\maketitle
\tableofcontents

\mainmatter
\include{./TeX_files/chapter01}
\include{./TeX_files/chapter02}

\backmatter
% bibliography, glossary and index would go here.

\end{document}

YAML Header from Index.Rmd page

title: "A Minimal Book Example"

affil: "College 1"

The problem is that when I knit (or Build pdf_book) from RStudio, the college name is not seen in the title page of the PDF book. I have tried various ways, but I am getting one or the other errors. I want to show two authors (along with their respective affiliation) on the title page of the book. But here, I can't display it even for one author when I compile it through TinyTeX in RStudio. However, when I compile the TexStudio code in TeXStudio using TinyTeX, it displays two authors and their affiliations correctly. How can I solve this?
