Hi Maks, this is Kimberly. I'm glad to assist you today.
Try this command to fully reinstall the Windows Settings app without reinstalling Windows itself.
Press Win + S, type PowerShell,
right-click Windows PowerShell → Run as administrator.
Copy and paste this command, then press Enter:
Get-AppxPackage windows.immersivecontrolpanel | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Once it completes, restart your PC.
If the command gives any errors, you can also reset all built-in Windows apps (including Settings) by running:
Get-AppxPackage -AllUsers| Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Should you have more questions, please let me know.
Best regards,
Kimberly
