Additional context

Start by reproducing the failure on macOS using the listed R commands, the r.rpath.mac setting, and the reported VS Code and extension versions. Trace the command entry points for "R: Run Command in Terminal" and "R: Run Command With Editor Path in Terminal"; done means both commands run code successfully in the R terminal without an error dialog.
