Started after I upgraded to macOS 14. When I close the lid of the laptop and leave it for a couple hours, it's not locked when I open the lid. Seems like a pretty big security flaw...
Not sure if the laptop stays on or not though, battery settings shows no battery usage for the 6-7 hours it was closed.

I'm having a similar issue. Most of the time, shutting the lid puts my MacBook Pro 2020 to sleep. But sometimes, it doesn't. Today I came back after the lid had been shut for over eight hours and the screen wasn't locked when I opened it.
I'm running Sonoma, 14.0
The MacBook was on mains power until just before I shut the lid, and was left untouched until I opened it this evening. Although the battery showed no drain, the screen was unlocked.
I did check that; it is set to 'immediately'. I noticed that if I close the lid very slowly, I can't see the screen turn off.
I ended up rebooting to see if that would work, and surprisingly it took care of the issue. Now if I try to close the screen slowly, once it gets to about 1 inch open, I can see the screen go dark and it will be locked when I open the lid again.
Haven't been able to recreate this issue now.
This has happened again overnight. From looking at the output of pmset -g logs and the install.log file, I think that my MacBook is actually sleeping:
2023-10-13 22:24:04+13 Noels-MacBook-Pro softwareupdated[524]: SUOSUPowerEventObserver: System will sleep
2023-10-13 22:24:04+13 Noels-MacBook-Pro SoftwareUpdateNotificationManager[960]: SUOSUPowerEventObserver: System will sleep
2023-10-14 09:46:29+13 Noels-MacBook-Pro SoftwareUpdateNotificationManager[960]: SUOSUPowerEventObserver: System will power on
2023-10-14 09:46:29+13 Noels-MacBook-Pro softwareupdated[524]: SUOSUPowerEventObserver: System will power on
This clearly shows the laptop going to sleep in the night and then waking up in the morning.
But for some reason the screen is never locked even though the settings clearly state that it should be.
Check this:
System Settings > Security & Privacy > Require Password...after sleep or screen saver begins.
