Research direction

Start by reproducing the hang in Visual Studio Code with the PowerShell script from the issue, then inspect the attached PowerShell Trace LSP.log, PowerShell.log, and StartEditorServices-27172.log. Done means pressing CTRL+C while stopped at $counter in finally no longer leaves the debugger and terminal hung.
