When trying to follow the steps given in https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/working_with_nrf/nrf52/gs.html to configure the DK, I am unable to complete step 3 of the 'Installing the sample' section as the Erase and Write option in the Programmer application is greyed out. The 'read' option also does not appear to be functioning correctly. I did the process correctly for two other identical chips purchased at the same time, but this only this one is not working correctly. I have attached the log file generated throughout the process and a screenshot of the Programmer application after disconnecting the device.
