Everytime at midnight fullscreen mode ends

[Crispy136]

Hi there, I have a strange issue with Sonoma on my Air M2. Every time I use an app, watch a video or do something else in fullscreen, exactly when the clock strikes midnight the fullscreen mode automatically ends and I have to switch back manually. This is perfectly reproduceable. It does not depend on how long has the app been in fullscreen, even when I start it at 11:59 it has the same issue.

Any advices for me?

Thank you!
