Compiling Marlin 2.1 on SKR 1.4 Turbo : package.json not found

Hello.

I’m trying to compile Marlin 2.1.1 for a SKR 1.4 Turbo

I have made a fresh install of Visual Code Studio + Platformio + Marlin Auto Build then restart VCS.

When I open the Marlin folder, Marlin Auto Build dectect the files but if I click on Build, I have this error :

PS D:\Imprimante_3D\Marlin-2.1.1-SKR1.4Turbo> platformio run --silent -e LPC1769
Error: Could not find one of 'package.json' manifest files in the package

Same error occure when I open Platformio tab, expand LPC1769 and click on build :

Executing task: C:\Users\Mikael\.platformio\penv\Scripts\platformio.exe run --environment LPC1769 

Processing LPC1769 (board: nxp_lpc1769; platform: https://github.com/p3p/pio-nxplpc-arduino-lpc176x/archive/0.1.3.zip; framework: arduino)
-----------------------------------------------------------------------------------------------------------------------------------------
Error: Could not find one of 'package.json' manifest files in the package

What’s wrong with my setup ?

Thanks.

After deleting :
%APPDATA%/Code
%USERPROFILE%/.platformio
%USERPROFILE%/.vscode
.pio folder in the Marlin folder

I don’t have this error anymore
