Hello Basic Haste,
Welcome to the Q&A forum.
From what you shared, I see you cannot open the Quick Settings menu. When clicking the Quick Settings button, a blank UI briefly appears and then disappears. Since creating a new local account didn’t resolve the issue, here are a few additional methods you can try:
1. Restart Shell Experience Host
Open Task Manager
End task:
Windows Shell Experience Host
StartMenuExperienceHost
They will restart automatically
Test Quick Settings again
2. Restore the default policy state

This could restore default Windows behavior for Notification Center and Quick Settings.
