It is going to the Default_Handler which is the dumping ground for ALL the interrupts you haven't explicitly provided a IRQHandler for.

You'll like have a dozen handlers, including WWDG_IRQHandler resolving to the same address. Review startup.s

Consider which peripherals and interrupts on them that you are enabling
