This is what I ~see~ get when I copy and paste what I see in the Console:

Shall we delete the ZIP file
([posit-dev-positron-workshop-project-e3ff127.zip](vscode-file://vscode-app/Applications/Positron.app/Contents/Resources/app/out/vs/code/electron-sandbox/workbench/workbench.html#))?

1: Nope
2: For sure
3: Not now

Selection: 
2
✔ Deleting
  [posit-dev-positron-workshop-project-e3ff127.zip](vscode-file://vscode-app/Applications/Positron.app/Contents/Resources/app/out/vs/code/electron-sandbox/workbench/workbench.html#).
✔ Opening [posit-dev-positron-workshop-project-e3ff127/](vscode-file://vscode-app/Applications/Positron.app/Contents/Resources/app/out/vs/code/electron-sandbox/workbench/workbench.html#)
  in the file manager.

Then nothing happens.

Maybe it's as simple as browseURL() not working with files in Positron?

This works in RStudio but not Positron:

browseURL("file://Users/charlottewickham/Desktop/posit-dev-positron-workshop-project-e3ff127")

It's probably this: https://github.com/posit-dev/positron/issues/5486

Thanks for the additional research @cwickham! That looks promising. Or, rather, "promising".

This is fixed by changes in Positron and ark, which are working their way through the system. In the glorious fullness of time (presumably the early August release), normal folks should reap the benefits.
