After successfully building and running the nRF9160 at_client sample app on Monday, I tried to repeat this success this morning but VS Code under Connected Devices says nRF Command Line Tools are not installed and does not show the nRF9160 board. Nothing changed from Monday that I can think of. I did try re-installing the nRF Command Line Tools, but nothing changed. Not sure what to do next.
I'm on a M1 Mac, but have installed the Intel versions of all software as I understand there are issues with the native M1 software. As I said, this worked the last time I tried it two days ago.
