My nRF 9160 DK is being detect by my computer. And my computer detects that the J-Link driver is connect. But the nRF 52840 is not appearing in file explorer. I'm not sure what to do

The only the J-Link driver appears in Device Manager

The board was working yesterday

I have tried using another cable and a different USB port
