I am receiving error when trying to interrogate bluezone 7.1. I do not encounter this error before until recently when trying to work on something. I am using Windows 10 version 1909 (OS Build 18363.836) and Pega Robotics Studio version 8.0.1110.0.
You'd likely need to upgrade to a later version to get support for Windows 10 1909. 8.0.1111 is nearing two years old and likely has issues with later builds of Windows 10 that have since been resolved.
