quarto doc does not finish rendering when r and julia chunks are used (RStudio & VSCode)

RStudio

I am trying to run R and Julia in the same quarto document. In RStudio, I see that the julia chunk is not runnable (no 'play' button) in the following quarto doc:

---
title: "Untitled"
format: html
---

```{r}
1+1
```

```{julia}
using DataFrames
```

I have JuliaCall package installed and julia 1.9.2 is in my system path (REPL runs outside RStudio). My R version is 4.3.1 and quarto version is 1.3.450. I am on Windows 10.

When I try to render quarto, the server keeps running but the document never renders. It seems to be stuck at chunk 2 that contains julia code. I understand that it is calling JuliaCall behind the scenes. But I don't see any result.

processing file: test.qmd
1/5                  
2/5 [unnamed-chunk-1]
3/5                  
4/5 [unnamed-chunk-2]
Julia version 1.9.2 at location C:\Users\USERNAME\AppData\Local\Programs\JULIA-~1.2\bin will be used.
Loading setup script for JuliaCall...

VSCode

VSCode does allow me running the julia chunk using the 'play' button. But it also gets stuck at Loading setup script for JuliaCall... when I try to render the test.qmd.

Start with the minimal test.qmd example and render it in both RStudio and VSCode, focusing on the JuliaCall setup stage where processing stops at “Loading setup script for JuliaCall...”. Done means the mixed R and Julia document finishes rendering in both environments.
