Run update to 10.15.4, reboot, and no update

[netdog]

Hi

Running 10.15.3 on a 2017 MBP.

Software Update indicates that 10.15.4 is available, and I click Update Now (and uncheck auto update to be safe), the machine reboots, seems to be updating, but not long after it comes back to the login screen. When I go to "About This Mac", it reports that it is running 10.15.3

Any ideas? I've got 12GB free, but I assume that's enough.
