You need to repair Microsoft app.
Go to Settings > Apps> Apps & Features. Look for the Microsoft App ( In my case, it's Microsoft 365 App). Click on it and click modify. IT's going to ask you to see if you allow the app to make changes. Click "Yes" and click on the Online Repair. Once the repairing is done, reboot your system and you should be good to go!!
