Pb compiling VSC/PlatformIO

Hi everyone,

I’ll need your help: I’m totally new to the VSC / PlatformIO environment (although not into programming) but I’m having a weird problem.

I followed all the tutorial given to install / configure my VSC / PlatformIO for programming my Nibble. I’ve created the test project “hello world” :

#include <Arduino.h>
#include <Nibble.h>
#include <Display/Display.h>

Display* display;
Sprite* sprite;

void setup() {
  Nibble.begin();
  display = Nibble.getDisplay();
  sprite = display->getBaseSprite();
  sprite->clear(TFT_BLACK);
  sprite->setTextColor(TFT_WHITE);
  sprite->setTextFont(2);
  sprite->setCursor(0, 0);
  sprite->print("Hello world!");
  display->commit();
}

void loop() {
  // put your main code here, to run repeatedly:
}

But it cannot compile due to many "locked files cause accessed by another process ":

I thought it was a basic problem, but nothing found on my differents webcrawlers(or maybe I’ve not used the right keywords or sites)…
I’ve tried to inactivate my anti-virus but the problem remains.
I’ve also tried on another computer : same issue !

Is there anyone who knows how to fix this problem?
Thanks in advance !
