i add this but the code is Being stuck in while loop

it means the NRF_CLOCK->EVENTS_HFCLKSTARTED is zero

what is the problem?

hardware side?

It means that you external oscillator is not starting or giving a stable clock. Yes, sounds more like a hardware related issue with the external clock or the connections to it.
