Macbook Pro 2019 no keyboard backlight options in System Preferences

My MacBook Pro 2019 no longer displays any keyboard backlight options in System Preferences. The keyboard lights up briefly at the login screen then turns off. I have no keyboard backlight options in System Preferences, they are missing. The backlight-keys on the Touch Bar have no effect. Keyboard brightness slider in the the tool bar returns to 0 brightness after trying to slide over.

See if the problem still happens in Safe mode (press and hold the shift key down at startup). It can take much longer to safe boot (5 min) so be patient.

How to use safe mode on your Mac - Apple Support

Safe mode very often corrects weird software behavior by forcing the OS to do cache clearing and other housekeeping. When you're in safe boot, the machine will not be at its best performance, especially with graphics, but that's expected.

Does the problem persist while in Safe mode?

Often not required, but consider allowing the Mac to "soak" in Safe mode for an hour to allow maintenance routines and processes time to complete, then exit safe mode by restarting your Mac normally and re-evaluate the issue again.

D.I. thanks for responding,

Safe mode does not change the problem. Left it booted in safe mode for over 2 hours -- no change. This seems like an issue with the O.S. keyboard lighting options are simply not where they should be.
