Above given is a short version of the Arduino code I used in my ESP32-S3.
On some occasion I am getting a crash , but unlike any other crash this one is not restarting the Board itself - it is forever stuck at the crash.

Here is the crash Log:

Task running on core 0
Setup (runnning on 2nd core)Guru Meditation Error: Core 1 panic'ed (Unhandled debug exception).
Debug exception reason: Stack canary watchpoint triggered (ipc1)

I used ESP Exception decoder and found these :

can someone please explain what is wrong.
