Hi.

Did you also install the "nRF command line tools"? nRF Command Line Tools - Downloads - nordicsemi.com

I suffered from the same problem. I solved it by installing "nRF command line tools".

Specifically, you need two system passes and a reboot.

(for Windows)

1>>  C:\Program Files\Nordic Semiconductor\nrf-command-line-tools\bin\

2>>  C:\Program Files\SEGGER\JLink

I wish you all the best and hope this helps you.
