Hello everyone, for some context, im trying to use a raspberry pico as a probe to upload a firmware into another pico, i have a blink code to test this, but im getting the error

  digitalWrite(PICO_DEFAULT_LED_PIN, LOW);
  delay(100);

if someone knows anything, please help

Does this also happen without this or with lower speeds?

so, I tried to remove the argument and this happens debug_speed = 5000 this error happens
