I have around 20 sites and it broke “only” 2 of them.
Those 2 had Polylang installed and when a Wordfence Scan started, it never finished and the site became unavailable.
According to the amount of new topics recently, I assume that the newest Wordfence version has problems with many plugins and/or themes, but thats just my theory for now.
We had the same issue after updating from Slider 2.3.7 to 2.3.8 (using ElegantThemes Divi).
Tried 2.3.9 as it just came out and working fine, thanks for acting that quick. 😉
