Hi,
This issue usually happens because of a corrupted or unresponsive Windows Settings component, or a service conflict after an update, which can cause the Power & Sleep page in Windows Settings to freeze or not load properly even after restarting.
1. Restart explorer.exe
On your keyboard, press Ctrl + Shift + Esc.
Go to the Details tab.
Scroll down and find explorer.exe.
Right-click on it and select End task.
In the menu bar, click File.
Click Run new task.
Type explorer.exe and press Enter.
2. Reset Settings via PowerShell (Admin)
Right-click the Start Menu and choose Windows PowerShell (Admin).
Copy and paste the command below, then hit Enter:
Get-AppxPackage windows.immersivecontrolpanel | Reset-AppxPackage
Restart your computer then check.
3. Run SFC and DISM to check and repair system corrupted files:
Open Command Prompt as an administrator.
Copy and paste each command below, then press Enter. Please run each command one at a time:
DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow
Restart your PC
4. If that fails, the next step is to try System Recovery without deleting your files and apps.
Click the Start menu > Settings > System > Recovery.
Choose Reinstall Now under the section labeled 'Fix problems using Windows Update.'
Once completed, your system will restart. Please check afterward.
