ESP32-WROOM - Problem using multiple cores

Question

I am having issues with my code for an ESP32 Wroom. I am trying to use both cores on the esp to speed up and create an efficient process for the device; one core checks for a change/response from a website page. and the other changes the led patterns according to the response received.

Core 0 (getting response) should be constantly updating a string called "payload" with the latest received information form the website. this is happening whilst the other core is displaying a pattern until it receives a change in "payload"; and changes accordingly.

the issue i am having is that the esp after uploading and first time starting prints the following message every 1-2 seconds:

rst:0x8 (TG1WDT_SYS_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:DIO, clock div:1
load:0x3fff0018,len:4 
load:0x3fff001c,len:1044 
load:0x40078000,len:8896
load:0x40080400,len:5816
entry 0x400806ac

This is also printed in some of the messages:

Guru Meditation Error: Core 0 panic'ed (Double exception)

I am new to ESP32's and have not much experience with Arduino, does anybody know what I am doing wrong or ways of achieving the same aim avoiding the current issues. Thanks in advance.

Here is the code for my project.
