platformio-vscode-ide Failed to install Platformio IDE in vscode


  • I'm using platformio IDE in vscode.

  • Before 2019.10.11, the platformio IDE extension worked well.

  • But after 2019.10.11, every time I open vscode I get this message.

Installing PlatformIO Core...
Please do not close this window and do not open other folders until this process is completed.
