Anyone know the meaning of this error message? How can i fix it?

"Sending S2 multicast: Attempt by method 'HSPI_ZWave.ZWaveAPI.FUNC_ID_ZW_SEND_DATA_MULTI(Byte[], Byte[], transmit_options_values, Boolean, Boolean ByRef)' to access field 'ZWave.BasicApplication.SecurityManager._rngCryptoServicePro vider' failed."
