HA stopped working... Can't connect

Now my Pi3 has stopped working. It’s not showing up in my router’s connected devices list.
Here is the error I’m getting with a monitor connected.

Sounds like a corrupted SD card I’m afraid

That’s what I figured as well so I formatted a new card and copied Pi3 32bit image and still cannot connect. Not showing up in router list. Need to connect to a monitor this afternoon…
