If this is affecting Word, Excel and PowerPoint, then the best option is to perform a full repair of your Office installation.

Open the Settings App (gear icon on your Start Menu)

Go to Apps, then scroll down to find Microsoft Office

Select that and choose Modify - Online Repair.

That should fix any issues with your Office Installation.
