Hi, I am an Independent Advisor, and welcome to Microsoft Q&A.
I understand that you are experiencing issues with your Microsoft Word.
Please close all Word files.
Try a Quick Repair for Microsoft Office.
Follow the steps below.
Press Windows + R, type: appwiz.cpl
Locate Microsoft Office / Microsoft 365 > Change > select Quick Repair first.
If it is still not working, run Online Repair. Online Repair will uninstall and reinstall your Microsoft Office Suite. This method will take longer to complete.
