Screen blanks after only 30 seconds of inactivity since the last update (Gnome 43)

Hi! Since the last update (stable 2022-11-14, shipping Gnome 43) the screen is blanking after only 30 seconds of inactivity .

However the Screen Blank (in Settings > Power > Power Saving Options ) is set to 15 minutes. I tried disabling it completely but it doesn’t work.

This is happening when on battery power and when plugged in.

Do you have any idea how to fix it?
Thanks!
