Hi karinga,
If the only issue you were having was with the Microsoft Word app, it is more likely that the app itself may have been the issue.
However, we do have some steps for you to use to check your user profile.
1. What we want to do is try starting up in safe mode, as safe mode does some system checks, and can sometimes resolve issues. How to use safe mode on your Mac
It may take longer to finish the start up, and you'll also see some differences in the display. This is expected with safe mode, and when you restart normally, they'll be gone.
Test the app, and then restart your Mac normally to end safe mode, and test again.
2. Disk Utility can scan your system disk and verify or solve issues. How to repair a Mac disk with Disk Utility - Apple Support Follow the steps on that page to run First Aid.

Take care!
