R Shiny - Downloading a PDF Report Error

I'm getting the same error when trying to download a PDF report from within a Shiny app. This other post suggests rolling back to RMarkdown 1.8

New problems producing pdf from Rmarkdown

I updated all of my packages and now have encountered new errors when attempting to generate pdf documents from Rmarkdown (called from a Shiny app). I installed tinytex in an effort to correct these issues and have ceased to be able to produce pdf reports at all. (Rmarkdown html output still works fine.) Can anyone tell from the following error message what my problem might be and how to correct it? Thank you!
