If necessary, download the Microsoft SARA-Tool for simple bug fixes to make sure that all old Office versions are completely uninstalled. Microsoft gives a detailed guide on how to uninstall all old Office versions.

Hint: This is also necessary if the Windows is a fresh installation, and you never used the Microsoft 365.
