Device could not be powered up

no flying leads, no shorts, no static - suddenly my device behaves this way

is this something I could have done

is there a cure,

I build a new project for check - same error

from manual:
Device could not be powered up
Debug block on the device could not be powered. Debug block on the target is not working properly. Mainly caused by target problems: debug block not powered and clocked properly.
