Compile Multiple PDF using RMarkdown LaTex Error - r

Question

I am trying to automatically compile multiple individual PDF reports from RMarkdown using a for loop in a separate R script. There appears to be an issue using the kable_styling() function from the kableExtra package when compiling multiple reports, but not for a single report.
This is the render loop in a separate script:
mtcars = data.frame(mtcars)
for (car in unique(rownames(mtcars))){
rmarkdown::render('mtcars_report.Rmd', # file 2
output_file = paste("report_", car, ".pdf"))
}
Here is the YAML header used for all reports:
title: "mtcars_report"
output:
pdf_document: default
html_document:
df_print: paged
header-includes:
- \usepackage{booktabs}
- \usepackage{longtable}
- \usepackage{array}
- \usepackage{multirow}
- \usepackage{wrapfig}
- \usepackage{float}
- \usepackage{colortbl}
- \usepackage{pdflscape}
- \usepackage{tabu}
- \usepackage{threeparttable}
- \usepackage{threeparttablex}
- \usepackage[normalem]{ulem}
- \usepackage[normalem]{ulem}
- \usepackage[utf8]{inputenc}
- \usepackage{makecell}
- \usepackage{xcolor}
geometry: margin=.8cm
This RMD code works with this loop and renders each PDF:
knitr::opts_chunk$set(echo = TRUE)
library(rmarkdown)
library(dplyr)
library(kableExtra)
mtcars = data.frame(mtcars)
cars = mtcars[rownames(mtcars)==car,]
{r, echo=FALSE, message=FALSE}
cars_table = cars %>%
select(mpg, cyl)%>%
t() %>%
kable("latex")
cars_table
This add a kable_styling command, the PDFs do not render:
cars_table = cars %>%
select(mpg, cyl)%>%
t() %>%
kable("latex") %>%
kable_styling(latex_options=c("striped", "float_right", "hold_position"),full_width = FALSE)
cars_table
I get this error: ! Undefined control sequence.
\rowcolor
If I knit the RMD as a single file without the loop (i.e. cars = mtcars[rownames(mtcars)=="Merc 280",] it DOES work with the kable_styling . It just appears to be an issue when I try to render it with the loop. I have updated all packages to my knowledge running:
update.packages(ask = FALSE, checkBuilt = TRUE) # update R packages
tinytex::tlmgr_update() # update LaTeX packages
