Lots of users are complaining about this issue. It's possible the learning algorithm has kicked in again after the update, in which case give it between 7 and 10 days to learn your usage pattern. Some users have mentioned turning off some or all of the AI features, especially base S23 users with the smaller battery.
Try wiping your cache partition. Recommended after any update
You would need to plug into a working PC or laptop

Note: half the time, it's down to a 3rd party app or customisation that's not developed properly for the new update. If you have any of these then uninstall and monitor.
My S23U is perfectly okay with the new update. However it is stock UK, never flashed or rooted and with no customisations. Ai is all running fine.
