The type of board you are using.

ESP32 Devkitc V4

What IDE are you using?

Arduino IDE

What IR protocol are you using?

NEC

Pin(s) used for IR-receive, if not default.

Arduino pin number: IO4

The library version you are working with.

I use the latest Arduino library version 4.4.1 and verified this!

What are the steps to reproduce this issue?

1. ESP32 Arduino Core 3.2.0
2. Using IRremote and Adafruit_NeoPixel to change LED color and brightness
3. IRremote pin = IO4
4. WS2812 LED pin = IO0

What happens?

After the board is turned on, as soon as the LED lights up (Adafruit_NeoPixel::show() ), the board will restart
Note: There is no problem if ESP32 Arduino Core 3.13 is used
