Sleep mode disappeared on Microsoft Surface Laptop 7

Question

My sleep mode disappeared completely, so PC won't shut down and drains battery 10 times faster (so instead of promised 10 hours (even though they advertise 20) I have 2 hours of battery).

I tried different solutions found on the internet such as modifying gpedit, updating display driver, checking regedit, none of that helped. All Microsoft updates are installed. All firmware or laptop updates are installed.

When I close the lid the laptop turns off the display, but keep working so I get all notifications and the laptop can even reboot after updates installation.

I know that reinstallation of Windows 11 would probably help, but that shouldn't be the only solution, it also implies a lot of effort to have apps reinstalled.

There are errors in the Power Energy Report (below), but I don't know how to resolve them as indication is not clear.
