I met such a situation: In the use of JLink burning program or air upgrade, after the completion of the program card died in initialization low-frequency crystals.
"sd_softdevice_enable(p_clock_lf_cfg, softdevice_fault_handler);"

Have you confirmed that you have the correct load caps for the external crystal? I have never seen this issue before, i.e. that the XTAL does not start up correctly when you set NRF_CLOCK_LF_SRC_XTAL as source, provided that a crystal with the correct specs and the correct load caps are used.
Have a way to remove NRF_CLOCK - > LFCLKSTAT status?
Could you clarify what you mean with "remove NRF_CLOCK->LFCLKSTAT"?
What method can make NRF_CLOCK->LFCLKSTAT == 0?
Triggering the TASKS_LFCLKSTOP task, i.e. NRF_CLOCK->TASKS_LFCLKSTOP = 1;
should stop the LFCLK.
