It looks like your platform or the platform packages are broken.
- Close VS Code
- Delete the content of
D:\PlatformIO_Core\packages - Delete the content of
D:\PlatformIO_Core\platforms - Start VS Code
- Wait until PlatformIO performed all necessary tasks
Note: Your path “D:\PlatformIO_Core” is very unusual!
Usually this folder is located at “C:\Users\<username>\.platformio”.
Maybe your whole PlatformIO installation is broken and should be reinstalled.
Again: When you post code, logs ini-files etc, please use the preformatted-text feature!
This makes your code much more readable and avoids error in formatting.
Thanks in advance!
