Thanks Thomas.
Your office version is way outdated, to the point that Updater wouldn't be able to update it basically. It is a discontinued version. When a version is discontinued, it means updates won't be pushed to it, hence it doesn't update.
Anyway, it is solvable.
What you need is to uninstall and reinstall.
The reason I asked where you purchased is because it determines how you reinstall.
If you signed up via Apple App Store, then download and install from the App Store.
If you signed up via Microsoft directly, please go to https://www.office.com
Sign into the Microsoft account you used for the subscription. Click on the 9-dot icon on the upper left > More apps.
Then on the upper right, click on "Install apps". This will now download the installer file. Once downloaded, click on the file to install. It will install the Desktop version of the apps for you then.
If for any odd reason it still doesn't work, download and run the updater https://support.microsoft.com/office/office-for-mac/troubleshoot-microsoft-autoupdate-in-microsoft-365-and-office-for-mac?apid=ets
