Could not initialize project invalid params

Looks like your platform is broken

  • close VS Code
  • delete .platformio\packages\framework-arduinoststm32
  • delete .platformio\packages\framework-cmsis
  • delete .platformio\packages\gccarmnoneeabi
  • delete .platformio\platforms\ststm32
  • start VS Code
  • reinstall the STM32 platform

where .platformio is located at C:\Users\<username>\

I have followed the steps but the problem is not resolved

Open a Core CLI and execute

mkdir test_project
cd test_project
pio init -b genericSTM32F103C6 --ide=vscode

what’s the output?
