There is an issue with LabVIEW 2023 Q3
The response we got from NI regarding this issue was
It is to do with the version of a certain component/dll “niMDKScripter”
The version that comes with LabVIEW FPGA 2023 Q1 cannot build DFIR graphs in LV 2023 Q3. This is what the error in your image also points to.
Solution:
Replace the existing DLLs in the NI folder C:\Program Files (x86)\National Instruments\LabVIEW 2023\Targets\NI\FPGA\RIO with the 23.5 version of the niMDKScripter DLL, attached.
Note, if using 64-bit the path should be updated to :\Program Files\.....
Please ask NI for an official patch, or the updated component, and see if that helps.
