there is one known bug that will be fixed asap (which allows dev mode in

off completely in the UI or set a password to work around this for the
time being. [1]
This is if you flash with --developer-mode, but don't have a password
set? Note, you won't be able to turn off the developer mode switch,
until you set a PIN/password. And even though it's already in the "on"
position, once you set a PIN/password, adb doesn't seem to start
automatically, so it will have to be toggled off, then on again, to
enable adb.
