A problem from internal software in RT VI (Invoke node in stockFPGA)

Hi, everyone

I'd like to know what this error means..

I didn't change anything on FPGA and RT VIs supported from NI.

Error message below

An internal software error has occurred. Contact National Instruments technical support at ni.com/support. Error details:

Method Name: <b>Create from Data Type</b>

Thank you
