Sorry for late response, was on vacation. Please post a log/screenshot with Jlink Commander, not nrfjprog.

Looks like it is protected.  You are using a very old software which is no longer support for a long long time.  It may not able to unprotect the nrf52840.  You need to use nrfjprog for that.
