Using `rmarkdown::render()` on two `.Rmd` reports to `.pdf` in the same session causes crash.

[djslp]

I am attempting to use rmarkdown::render() to on two nearly identical .Rmd files and output them as a .pdf. The example can be seen below.

rmarkdown::render("/path/to/project/Project_Name/rmarkdown_1.Rmd",
                  output_file = paste0("/path/to/project/Project_Name/Output/", 
                                       Sys.Date(),
                                       "_rmarkdown_1.pdf"),
                  intermediates_dir = "/home/service_account/")

rmarkdown::render("/path/to/project/Project_Name/rmarkdown_2.Rmd",
                  output_file = paste0("/path/to/project/Project_Name/Output/", 
                                       Sys.Date(),
                                       "_rmarkdown_2.pdf"),
                  intermediates_dir = "/home/service_account/")

The first .Rmd file renders with no issue. When rendering the second, the console hangs for a few seconds, then the error is presented.

# Here is the successful message for `rmarkdown_1`

I was unable to find any missing LaTeX packages from the error log 2020-12-09_rmarkdown_2.log.

Is there any documentation or solutions for this issue?

I can adjust the control flow to execute each process in two separate sessions, but wanted to raise this issue to see if there is a solution for it.
