but : Task watchdog got triggered

# idf.py flash monitor
...
E (5733) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time:
E (5733) task_wdt: - IDLE0 (CPU 0)
E (5733) task_wdt: Tasks currently running:
E (5733) task_wdt: CPU 0: btController
E (5733) task_wdt: CPU 1: IDLE1
E (10733) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time:

E (10733) task_wdt: Tasks currently running:
