I am unable to connect the device to nRF Connect programmer. Following is the error. how to resolve it? what actually is the problem?

If you have used the cable with other DKs before, then it should be fine.

As a reference, you can have a look at the Get started section of the nRF5340 DK, which will guide you to the Getting started with nRF Connect SDK guideline.

Do you have the Toolchain Manager and a nRF Connect SDK installed? You could open a bash as shown in the picture below

and use the following command:

nrfjprog --version

Do you get a result similar to that?

$ nrfjprog --version
nrfjprog version: 10.12.1
JLinkARM.dll version: 6.88a

By the way: are you operating on Windows 10?
