First of all, I recommend that you carry out an update and then an Office repair.

If none of these help, here is a link with additional steps you could take.

Uninstall Office automatically

If you need to reinstall Office, select the version you want to install and follow those steps: Microsoft 365, Office 2019, Office 2016, Office 2013, Office 2010, or Office 2007.

 

Thank you for your understanding and patience
