Are you able to replicate this issue on another PC or system?

Hi,

I have checked and have no other instances of VSCode (or nrfutil or any JLink instances) runnning in the background. I have also restarted multiple times since then.

But if you cannot replicate the issue on your side, i guess it is an issue with my system somehow..

Thanks,
- Fabian

Hi,

There have been similar issues reported when multiple J-Links were connected simultaneously along with several active VS Code instances. So, could you try to maybe close all VS Code instances and other Nordic tools, and also making sure there are no multiple J-Link instances.

Hi Priyanka,
I ran self-upgrade and got:
nrfutil is already the newest version (8.1.1)

Hi,

What nrfutil version do you use?

Could you try to update your nrfutil version?
