Run No Evil: Failed invoking <symbol> / Symbol Not Found Error

I get this error with any (initial) attempt to run a test with Run No Evil. (If I switch devices, either by selecting multiple devices up front or stopping and restarting with a different device, it will just run forever.) This has occurred with projects ranging from the Steps Carousel from [USER="51281"]peterdedecker[/USER]'s unit test tutorials, to a simple watch face with none of my own code, and with tests including none, a trivial case (print something and return true or false), and actual business logic.

Windows 10
Eclipse Platform 2018-12 (4.10.0.I20181206-0815)
Connect IQ SDK 3.0.8 (but also occurred with 3.0.7)

The Eclipse Platform Installation Details state CIQ IDE 3.0.6 and CIQ SDK Manager 3.0.6, though the Release Notes for each state v3.0.4. Eclipse reports that no updates are available. The following URL is in my available software sites: https://developer.garmin.com/downloads/connect-iq/eclipse/
