Board
ESP32-S3-Touch-LCD-4.3B
Device Description
Waveshare ESP32-S3-Touch-LCD-4.3B with a Sensirion SEN66 sensor connected with I2C
Hardware Configuration

Version
v3.1.3
IDE Name
Arduino IDE 2.3.6
Operating System
Windows 11
Flash frequency
80 MHz
PSRAM enabled
yes
Upload speed
921600
Description
I'm running the I2C sensor on Core 0 and LVGL on Core 1. Both running on their respective FreeRTOS task. Despite using vTaskDelay on both of them, Core 1 will always trigger the watchdog. These tasks are initiated on the default setup() and on loop() is only the lv_timer_handler(). The lvgl task updates dozens of objects and this seems to be the cause of the timeout, but adding vTaskDelays in between sections of this task doesn't fix it. Core 0, even with much longer times on the vTaskDelay, doesn't ever trigger a timeout.

}
void loop(){

Other Steps to Reproduce
I've had this problem with another board before, using the same ESP32-S3, when trying to use both cores. Any attempt at turning off the watchdog failed on that board too. That board is ESP32-S3-Touch-LCD-4, also by Waveshare.
