Failed to change notification settings in Windows 11

[Brizion2111]

When I right click on the bell at the end of the taskbar, and choose "Notification settings", the Settings app window opens for a fraction of a second and then disappears.

Re-register Settings app using PowerShell command:

Get-AppxPackage windows.immersivecontrolpanel | Reset-AppxPackage

Let us know if this helps!

Sometimes, a simple restart can resolve temporary glitches or conflicts that may be causing the Settings app to close unexpectedly.
