Installation error: VS Code / MacOS

Hello all, I’m trying to install platformio in VS Code on MacOS (10.15.2). Am prompted to reload the window on multiple occasions which I do, but am also asked to restart VS code. When I do I get the error message:

PlatformIO IDE installation has been suspended, because PlatformIO IDE Installer is already started in another window.

I’ve installed and reinstalled, I get the same error every time.
Anyone know how to fix this?

Try to close all VSCode windows and start VSCode again.
