This issue caused by the update of gRPC LabVIEW packages to version 1.2.5.1, affects the Measurement Plug-In Client Generator tool, as the Client generator uses the Enumerate Services API to get the list of available V2 measurement services.

It's working fine with v1.2.7.1, and I don't see any crashes.
