Re-downloaded 1.8.5 as you suggested. The builder does not load, only displays a blank white screen. Disabled all plugins, same results. Tried creating a new site from scratch, same results. Please reference the same problem another user is reporting WAIT: Loading Issue After Updating Bricks Builder from Version 1.8.4 to 1.8.5 - #4 by Lenglemetz .
Please do a more complete job of testing your software, and again, slow down on the rapid pace, fix the bugs first. No fun explaining to clients why their sites break constantly with each upgrade of Bricks.
