Hey,
I've tried restarting my iPhone 14 Pro and that seemed to have fixed the issue at first. After locking it and unlocking it, though, the issue persisted. I turned off Auto Brightness and that actually fixed the issue.
While it's not a permanent fix, you'll probably be able to use your phone without having to set the brighness up every time you unlock it. At least until they launch a fix for the issue.
Kind regards,
D.
