app_error_fault_handler at 0x00024a44

Good Day

We have an issue where our device will run normally in a full load condition for about 2 hours without issues but will suddenly go into the app_error_fault_handler. We had an infinite loop there allowing us to inspect it and we saw the handler is called from 0x00024a44 which is a Soft Device address. We tested this 3 times and it always failed at that exact address.

This is Soft Device version s140_nrf52_6.1.1_softdevice

We don't know how to debug this issue, any pointers for the nature of this error would be greatly appreciated.
