Python controller unpair failed with ChipStackError: src/lib/address_resolve/AddressResolve_DefaultImpl.cpp:124: CHIP Error 0x00000032: Timeout

[Saravana-kr22]

Description
When executing the script TC_Android_pair.py as a part of stress testing, unpairing function is failed with the chip.exceptions.ChipStackError: src/lib/address_resolve/AddressResolve_DefaultImpl.cpp:124: CHIP Error 0x00000032: Timeout error. This script will mimic on a high level how the pairing occurs in the Android ecosystem.

GitHub hash of the SDK that were being used are : 92f9f0b

Platforms
I Have performed the execution on Raspberrypi using ble-thread provisioning
Test Bed :
Controller Platform - python controller running on Raspberrypi 4B -8GB,
Nordic Board as DUT - all-cluster-app running on Nordic nrf52840-DK board
Provisioning method - ble-thread

Test scenario
Pair/Provision the DUT (All-cluster-app running on raspi) as per Android pairing flow using Ble-Thread.
Read device information after the device is provisioned
Unpair the DUT (i.e. removing the fabric)
Factory reset the DUT
repeat step1 - 6 for 500 iterations
