I am trying to prepare a paper template using R Markdown and Latex for the upcoming semester. I learn as I go through and the recent problem I am facing is the error message of ! LaTeX Error: Missing \begin{document}. Error: LaTeX failed to compile paper_template.tex when I knitr my Rmd file. Here is the code for the R-Markdown file;

abstract: ""
output:
pdf_document:
latex_engine: xelatex
includes:
in_header: customized_paper_template.tex
date: "2024-06-29"

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)```
