Interface 7885 not working


I just updated to build 7885 and although I’m in the system (I can hear music in the room ‘Rust’), I see nothing but a blank screen and mouse trails. And I cannot bring up any windows, not even preferences, nor the login window.
Here’s my system details:

Macbook Pro 2.9ghz
8GB ram
High Sierra 10.13.3
Intel Iris Graphics 6100 1536 MB

It did work previously
