Arduino ide2 library path too long: windows 10

Software IDE 2.x
1

I think this is the issue - I am trying to follow a tutorial on using the ESP32 sense boards from Xiao (https://www.youtube.com/watch?v=qNzlytUdB_Q). When trying to test the board (with simple flashing LED) the interpreter claims it cannot find a library.
From research, this seems to be related to the very long pathname in the installation of the ESP32 library. I am using the latest version (2.2.1) of the IDE.
Is there any way to change the install directory?
Thanks,

Welcome to the forum

Please post the sketch that you are compiling and the full error message, using code tags for both to make them easy to see and copy for examination

Hi, the sketch is the example-basic-blink, with no changes:

/*
  Blink

  Turns an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:

  This example code is in the public domain.

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(1000);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW
  delay(1000);                      // wait for a second
}

The error message is:

What exactly have you got the target board set to in the IDE ?

Hi, thanks for the comment. It is set to the xiao_esp32C3, as in the tutorial on youtube.
Regards,
Barry

That is not what it is set to in the video

Hi, true - my typo - but the result is similar using xiao_esp32s3:
