Dark Screen With Annoying Clock Display At Night

[anpease]

Hi,
I have an S24 Ultra and for the last couple of weeks the display on the screen skips my lock screen and displays a black screen with a clock on it. This is really annoying, especially at night as it lights up my room (I don't really want to turn the phone off at night).
I have spent ages searching for a solution, have turned Always On Display on and off, but with no success.
I would be extremely grateful if someone can tell me how to get rid of this, please?
Many thanks.

Could this be an app that you have downloaded doing this?

I haven't downloaded any new apps for quite a few months now, and this only started up a couple of weeks ago,
