Thank you, Ali. Even if SFC shows the system is fine, a repair install still helps fix Windows issues. You can also go to Settings > System > Fix problems with Windows Update, which is technically the same method if it is suitable.
Also, making a new user account can be tried.
- Open the Settings app by clicking on the Start menu and selecting the gear icon.
- Click on "Accounts."
- Click on "Family & other users" in the left-hand menu.
- Under "Other users," click on "Add someone else to this PC."
- Select "I don't have this person's sign-in information."
- Click on "Add a user without a Microsoft account."
- Enter a username and password for the new account.
- Click "Next," then "Finish."
