Quartus 18.1, cyclone V hard processor lost pinouts in Qsys

Mature design utilizing Quartus 18.1 and a Cyclone 5 (5cseba6u23i7n). Built many times and suddenly stopped with this error:

Error: system.acl_iface.hps: The pin information for the Hard Processor System could not be determined. Please check whether your edition of Quartus Prime supports the selected device.

Our licenses are valid and other designs without a hard processor work fine.

What is going on? Any clue?

    Have you tried Quartus 18.1 Standard which supports Cyclone V.

    The Quartus 18.1 Pro doesn't support Cyclone V.

    Uninstalled and reinstalled 18.1 (Standard both times) and restarted with a fresh checkout of the project and the error went away. Still not sure how I got it to give me this error.
