Hi DevZone,
I am having trouble programming samples to my nRF5340DK.
I decided to try validating my issue by using the Quick Start application in nRF Connect for Desktop, and saw the following failure, where the step for flashing Network core fails for the Peripheral LBS and Peripheral UART services.
The corresponding log file contents:

Not sure how access protection became enabled, as I used to be able to program various samples to the board.
`nrfjprog --recover` doesn't help.
Any ideas what to do?
