Hello
The AI answer did provide the correct repair instruction.
If repair doesn't work, do a reinstall.
In Settings > Apps> Installed Apps, uninstall your Msft 365 first.
Please go to https://www.office.com
Sign into the Microsoft account you used for the subscription. Click on Apps on the left.
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.
