Intellisense issues in VSCode

Bug description

Working on a qmd document with R in VSCode, I frequently get an error message relating to saving the .intellisense.r file. This message pops up often while editing various qmd documents. It does not happen when editing regular R code so I suspect it is an issue with the Quarto extension for VSCode. Clicking the 'overwrite' button dismisses the dialog but it pops up again soon after.

Steps to reproduce

Edit a qmd document containing R code blocks in VSCode with Quarto extension installed. At random times, the error message will pop up.

Expected behavior

Shouldn't see this error message.

Actual behavior

Get an error message from VS Code.

Reproduce the issue by editing a qmd document with R code blocks in VSCode and observe when saving the .intellisense.r file triggers the dialog. Start by tracing the Quarto VSCode extension's handling of that file during qmd editing; done means the overwrite error no longer reappears.
