I resolved this by creating a new appleid, a new bundle identifier name, and registering the device. Xcode, did the rest. I run the program on my device and I got the same error, HOWEVER, all the apps now showed up in Settings/General/VPN & Device Management and I was able to "Trust" the app. This is what was missing before I changed to a new ID. The simple "Hello World" default app didn't need to be trusted. Anyway, not everyone's solution but clearly something got broken and forcing a refresh with a different ID got things going. It could be interesting to go back to the original ID and see if the options are there to allow trusting of the app.
