When I configured the USART3 and LPUART1 it was going to the error handler function.
can anyone tell why that's happening.

@ukn.1 "it was going to the error handler function"
Do you mean the Hard Fault handler?
Lots of resources on debugging Cortex-M Hard Faults:

Note that this is not specific to the Disco board - the chip's internals work (and fail) the same way whatever board it's on. See this thread:
