Stuck on first attempt using MPLAB X (PICkit4)

[Demon]

mplabx is not a viable ide for pbp3. its useful to get mpasm and the mplab ipe only for mcs use.
if you want to use it as an ide for pbp3 then use ver 2.35 or older , none of which will allow use a pk4 of course

or use xc8 "C" with latest mplabx

Ah, that's why you use MPLAB IPE, as a programmer software to use PICKIT4. I don't get how you do in-circuit debugging though...?

MPLAB IPE keeps saying

The configuration is set for the target board to supply its own power but no voltage has been detected on VDD. Please ensure you have your target powered up and try again.

My Lab-X1 is powered, the LCD displays the old text from my last project on it. I must have something wired wrong, or I'm not configuring the IPE properly.

Gonna check that tomorrow. Time for bed. I can't even imagine how confusing this must be for newcomers.
