Hi

Just to make sure, what version of the nRF Connect for Desktop app do you have? There was an issue similar to this in v3.8.0 of the Desktop app, so try updating it to the latest version (v3.10.0) if you haven't already. 

A few other things you can try is to make sure all J-Link devices (and the Dongles) are disconnected from your computer before launching nRF Connect. Then launch the Programmer app and connect the Dongle to your computer.

If all else fails something might have gone awry when you first downloaded nRF Connect for desktop, try to uninstall nRF Connect altogether. Then make sure the folder C:\Users\___\AppData\Roaming\nrfconnect is empty or deleted before reinstalling nRF Connect for Desktop.

Best regards,

Simon
