S32K3 MCU secure unlock error

[KARL5]

I am using the P&E Cyclone FX programmer to unlock an S32K311 MCU that may be an abnormal part. When executing the script, an error is reported. Sometimes the script executes successfully, but even in those cases, the programmer still shows "Enable Secure" when connecting. Could you please help me investigate the possible cause? The error information is as follows:

Authenticating S32K3xx in Password Mode.

Have you ever get it to run? Are you trying to unsecure previsously secured device or it is somehow unexpected response? Do you have mutliple boards acting like this or it is just this one? Please provide further details. Thanks
