Interpreter details:

R 4.4.1

Describe the issue:

Maybe related to #4676. Seems to be a Windows only issue. I can confirm that this is a Positron or VS Code/Quarto VS Code extension problem as my RStudio runs normally, in line with the previous issue but different from @jennybc's results. I will try to provide more information than my predecessor. Please let me know if there is more info needed.

In a nutshell:

Positron/VS Code + Quarto + Shinylive + R = ×
Positron/VS Code + Quarto + Shinylive + Python = √
RStudio + Quarto + Shinylive + R = √

Steps to reproduce the issue:

Start a new folder for the Quarto project
Open the folder in Positron
Execute quarto add quarto-ext/shinylive in Terminal to install the Quarto extension.
Run install.packages("shinylive") if it has not been installed before.
Start a .qmd file
Include the following minimum quarto document, and render:

---
title: "Shinylive R test"
filters:
  - shinylive
---
```{shinylive-r}
#| standalone: true

7. You get an error.

## Expected or desired behavior:

Running normally as in RStudio.

It seems that there was no error from the Developer Tools console
