Agreed. All previous versions have worked fine for me, but the update I installed about 12 hours ago is not behaving correctly. When I got the update I lost my humanity-icons. When I try to change the icons I also click Auto Reboot and Save & Reboot. The banner only gets as far as saying "Setting up font". Then the banner goes away, and never proceeds to the next step. The customizer window remains open. Then if I manually close the window, a second customizer window immidiately launches. I am able to close the second copy normally. This behaviour is repeatable for me, even after multiple reboots.
