@fOmey - I have uploaded the sketch from Adafruit NeoPixel Library called simple.ino. Changed it a bit to display some different colors.

Using the devkit ESP32-S3-WROOM-2 that has an RGB LED on pin 38. It works fine. No issues here.

}

void loop() {
  pixels.clear(); // Set all pixel colors to 'off'

  // The first NeoPixel in a strand is #0, second is 1, all the way up

@SuGlider - Thanks for the quick reply.

I tested your example and same issue, however I did notice I was using debug mode instead of the verbose core debug level. Verbose has revealed a little more info:

I have imitated your board configuration settings and by disabling PSRAM, the rmtInit() error has disappeared:

[SuGlider]

E (555) rmt: rmt_new_tx_channel(269): not able to power down in light sleep is an IDF error message.
This is from esp-idf/components/esp_driver_rmt/src/rmt_tx.c:

#if !SOC_RMT_SUPPORT_SLEEP_RETENTION
    ESP_RETURN_ON_FALSE(config->flags.allow_pd == 0, ESP_ERR_NOT_SUPPORTED, TAG, "not able to power down in light sleep");
#endif // SOC_RMT_SUPPORT_SLEEP_RETENTION

It is due to some memory trash in RMT config struct.
It has been fixed with the PR #11203

Could you please apply this PR and let me know if this issue is gone?

@SuGlider - PR #11203 appears to have fixed the issue for me 👍
