This problem can be occurred in the following scenarios. 1. Run NFs(NRF/SCP/SMF/UPF/AUSF/UDM/PCF/BSF/NSSF/UDR) except AMF. 2. Run AMF 3. Run gNB/UE and try to register 4. STOP PCF 5. AMF Crashed AMF discovered the PCF through SCP during the UE registration process. At this time, ogs_sbi_nf_fsm_init() is not called, so AMF does not have state information about PCF. In other words, AMF state is NULL. In such a situation, when PCF is terminated at this time, a crash occurs as AMF attempts to change the PCF state. So, I've fixed that state information is initialized to solve this problem.
