[RESOLVED] Leonardo device not connected?

I ran my first sketch using the arduino ide and it performed as expected. To get the sketch to stop, I loaded in blink, which performed as expected.

Now I have lost visibility and access to the serial port that I was using earlier. USB7 showed up with Leonardo immediately adjacent to it. Now its gone.

I have no idea what I did wrong or how to fix it.

When I goto to device manager in W10, I find two hidden listings under usb, one showing a Leonardo (USB7), another showing a Leonardo bootloader(USB8). The are greyed out. When I click them, they show as code 45, this device is not connected to this computer.

I have tried rebooting W10, resetting arduino with the reset button, but cannot get the Leonardo usb 7 (or 8 which is bootloader) to show in port selections.



When I try to run blink on the only visible port which can "get board info", I get this
Arduino: 1.8.5 (Windows 10), Board: "Arduino Leonardo"
