Seeed Studio XIAO - ESP32-C3 program works while runing trough arduino IDE but not on a power source on it's own

I have been stuggleing with this problem as my current program for useing the XIAO with a WS2812 LED strip works properly when I run it trough Arduino IDE like it's supposed to but when I just plug it into a powersource (that be my laptop or a powerbank) the progam doesn't work properly. It seems to take 3 steps and switch inbetween those instaid of following the full range from dim to bright and back. I have no idea how to fix it as the program works when it's run trough Arduino IDE. I did use the FastLED libaray.

I use the following code:

#include <FastLED.h>
#define LED_PIN D10
#define NUM_LEDS 15
#define LED_TYPE    WS2811  //WS2811, WS2812, WS2812B
#define COLOR_ORDER RGB
#define CHANNEL     0
#define BRIGHTNESS 255
#define DATA_PIN D10

int ledPin = D10;


CRGB leds[NUM_LEDS];



void showLed() {
  for (int i=0; i<NUM_LEDS; i++ )
{
leds[i] = CRGB(239, 0, 255); //groen rood blauw
 uint8_t brightness = (exp(sin(millis() / 3000.0 * PI)) - 0.368) * 42.546;
  Serial.println(sin(brightness));
 if (brightness<5){
   brightness=5;
   FastLED.setBrightness(brightness);}
 else{
  FastLED.setBrightness(brightness);}

  FastLED.show();
}
}

void setup() {
  FastLED.addLeds<WS2812B, DATA_PIN>(leds, NUM_LEDS);
  Serial.begin(9600);
}

void loop() {
  showLed();
  
}

Below is how it is currently set up

Does anyone have a idea on what I need to do to give the LED strip a 'breating' effect when I plug it into a powersource?

Thank you in advance

Please show your schematic, including the power lines.
How do you power your board and your led strip?

Hi, sorry it took me a bit I have been buzzy with some other projects but I added a picture and a schematic. Let me know if you need anything els! I'm sorry if it's pretty clear that programming is not something I usaly do

@b707 is the addes schematic and picture what you had asked for? If not how can I improve it to make it more clear?

Sorry, I don't understand what is drawing in your picture

Hello, I have the same problem, have you found a solution?
The best solution I've found so far is to reset the card until it works, which isn't very practical.
