Update has not worked - Atom on Win 10

I have just upgraded to the latest version (as advertised on the home screen) of PlatformIO. Before doing so I had just built a project so it was working fine.

I now have the PlatformIO menu item but I am not getting the toolbar down the left, using ‘build’ does nothing and trying to go to the PlatfomIO Home screen (in the menu) also does nothing. I did not originally install via pip, I think I downloaded a binary but it was quite a while ago. I did not upgrade to V2.

Any suggestions to restore a working system?

Do you use PlatformIO IDE 2.0?
