ubiquity install fails at creation of user in 11.4

[E Cheddar]

hello, I got the message
Installer Crashed--we're sorry the installer crashed. Please file...
The progress indicator window said it had finished copying files, and failed at the point of creating a new user.
I tried it earlier, and got exit code 10. This time, there was no exit code.

and here is the syslog, says username setup failed with code 32
