I’m encountering issues using Quarto within Positron when trying to include R or Python code chunks in my .qmd documents. When I run the quarto preview command, I receive different errors depending on the language of the chunk.

Example .qmd File:

---
title: "Test Document"
format: html
---

## R Code

```{r}
print("Hello, R!")
```

## Python Code

```{python}
print("Hello, Python!")
```

Errors Received:

• R: I receive the following error when attempting to execute an R code chunk:

Error in dir.exists(x) : file name conversion problem – name too long?
Calls: … lapply -> FUN -> dir_exists -> -> dir.exists
Execution halted

• Python: When running a Python code chunk, I encounter this error:

PS D:\GitHub\testing> quarto preview d:/GitHub/testing/test.qmd --no-browser --no-watch-inputs
ERROR: Impossible to access to the file. (os error 1920): stat 'C:\Users\erik4\AppData\Local\Microsoft\WindowsApps\python3.12.exe'

What I've Tried:

• Verified that both Python and R are installed correctly and are in the system PATH.
• Checked project's folder permissions.
• Tried reducing the project path length, but the issue persists.

Thank you in advance for any help or suggestions!

R version: 4.4.2, Python version: 3.12.9
