bt classic discoveries (starting / stopping) causes unexpected reset

Development Kit: m5stack grey and m5stackcore2 used with ESPIDF
Module or chip used: ESP32 chip revision: 3
IDF version: V4.2
Build System: CMake

Power Supply: USB
##Problem Description
bluetooth classic discovery. Launching discoveries periodically on BT CLASSIC via esp_bt_gap_start_discovery(..) produces an unexpected RESET.

Our application is starting BT Classic discoveries. For example Start a Discovery of aprox 2 seconds each 3 seconds. All works OK (devices are founded, events are coming etc...), but in a not predictable time, can be 2 hours, can be 7 hours, the ESP32 Resets because of Guru Meditation Error: Core 0 panic'ed (Interrupt wdt timeout on CPU0)

I enclose a code that is crashing, and the crash LOG

Any Ideas???
Has someone encountered something similar??
