A recent security update\* for Windows 10 causes the robot controller communication to fail. Microsoft is working on a resolution and will provide an update in an upcoming security update for Windows. Meanwhile, ABB will provide a update of PC-SDK and OPC Server 6.06.01 that will fix the issue. The plan is to make it available mid-January.

A workaround is to manually uninstall the update. (Any of KB4056892, KB4056891, KB4056890, KB4056888, KB4056893. The updates contain the same fix but for different versions/builds of Windows 10.)
