Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello
That's because Microsoft 365 Basic doesn't come with Office apps like Word, Excel, etc. It is strictly for 100GB Onedrive storage only, so your Word app will not work.
YOu will need to use the web version for free in this case via www.office.com > Apps.
Or if you want the desktop version, you need at least Microsoft 365 personal, not basic.
