4G-5G Handover Failure due to Cause Insufficient-ue-capability

Hi Team,

4G-5G Handover Failure occurring due to band missing in container. It is abnormal that band going missing in UE capability after HO is initiated. Issue is not device sepcific and random.
Anyone facing the same issue? What can be the resolution path?
