Exception is noticed while executing xTaskRemoveFromEventList

Oh yes.
@phaneesh86 Recent versions of FreeRTOS come with more useful assertions which could help to narrow down the root cause problem that the list is invalid or got corrupted.
Another reason for internal data corruption might be invalid interrupt priorities when using FreeRTOS (FromISR) API in ISRs.
When in doubt see the FreeRTOS docs regarding RTOS for ARM Cortex-M and
e.g. Understanding priority levels of ISR and FreeRTOS APIs - #16 by aggarg which contains a pretty good explanation.
