Unable to run Nyxt built from source

[rustand2]

Describe the bug
Nyxt opens a blank (white) window and does not seem to work at all. I'm unable to make it respond to anything.
I found this other issue #3186 describing the same problem, but no solution was given.

Precise recipe to reproduce the issue

1. Clone the source and build it with make all.
2. Run ./nyxt

For website-specific issues:
Can you reproduce this issue with Epiphany / GNOME Web (https://wiki.gnome.org/Apps/Web)? N/A

The reason is that you're running a very old SBCL version.
