I’m running exactly the same build, but don’t have any problems. When you restarted, is PlatformIO trying to re-install itself? Has it successfully done so? You could open the developer tools Help -> Toggle Developer Tools, open the console tab, and then go View -> Command Palette -> Developer: reload window to see if there are any error messages on startup related to PlatformIO. Other than that, you could try renaming / deleting %userprofile%\.platformio\penv and restarting VSCode so that the extension reinstalls the PlatformIO core.

I managed to get it back by uninstalling all extensions - uninstalling vscode then doing a reinstall
when it opened a old project there was a window that said installing pio core - after that it was all back - WHEW a lot of work
