I am trying to knit documents in Rstudio. I have had no trouble knitting until now, and everytime I try to knit I get this message.

Error: ‘U’ used without hex digits in character string (:4:36)
Execution halted

This appears in every rmarkdown file I have tried to knit (I’ve tried 5+).

I have already tried reinstalling both R and Rstudio, but get the same problem. I have also tried knitting to pdf and word as well, but get the same error. I can also run code chunk just fine.

EDIT: Adding a Minimal Reproducible Example

---
title: "Untitled"
author: "----"
date: "2024-09-04"
output: html_document
---

```{r}
library(plotly)
p <- plot_ly(economics, x = ~date, y = ~unemploy / pop)
p
```

Trying to knit this results in the aforementioned error message:

“Error: ‘U’ used without hex digits in character string (:4:36)
Execution halted”
