After installing the 6.0.0 Beta 1 on my dev site I’m getting this “There has been a critical error on this website.” error. After downgrading PHP from 8.0 to 7.4, and also downgrading Wordpress from 6.0.2 to 5.9.4 I’m able to get the site back.
Prior to the downgrades, debug was showing me these errors:
