Nano 33 IoT restarts while running endless loop

Official Hardware Nano Family Nano 33 IoT

Hello all,
I am currently working on an Arduino IoT Cloud project where I want to connect two LED lamps.
I have broken down my code to an absolute minimum, because the actually simplest part just doesn't want to work....

// FastLED - Version: Latest 
#include <FastLED.h>
#define NUM_LEDS 24
#define DATA_PIN 12
CRGB leds[NUM_LEDS];

#include "thingProperties.h"

void setup() {
  
  Serial.begin(9600);
  delay(1500); 
  initProperties();
  ArduinoCloud.begin(ArduinoIoTPreferredConnection);
  setDebugMessageLevel(4);
  ArduinoCloud.printDebugInfo();
  
  FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);
  FastLED.clear();
  FastLED.show();
}

void loop() {
  ArduinoCloud.update();
  
  while(true) {
    for(uint8_t hue = 0; hue < 255; hue++) {
      Serial.println(hue);
      fill_solid(leds, NUM_LEDS, CHSV(hue, 255, 255));
      FastLED.show();
      delay(50);
    }
  }
}

What I currently want to achieve: the LED ring should simply iterate through all Hue values, creating a rainbow effect.
Unfortunately, my Nano 33 IoT does not behave as desired. After about 1 1/4 iterations, the Arduino simply restarts.
The debugging output shows me values from 0-254 and then from 0-~58, then it restarts.

This is driving me crazy. What am I missing here?

By the way, I know that theoretically I wouldn't need the While loop in this case. However, as I said, this is only a part from the actual code, in which I only run the rainbow effect as long as a button is pressed.

// Edit
I just tested it without the While loop. This is how it works. Can someone explain me why? And how I can make it run in a loop as well?

This seems to be an IoT Cloud problem, see Same code doesn't work when using IoT Cloud
