Hi Catherine,
Thank you for reaching out to Microsoft Q&A and providing details about your issue. This often related to accessibility settings, software glitches, or add-ins. First try to toggle Mouse Keys: This accessibility feature can interfere with keyboard input. Press the Option (⌥) key five times quickly to toggle it off. If enabled accidentally, this often resolves it. This seems to work for some Mac user: https://discussions.apple.com/thread/6605093?answerId=27326637022&sortBy=rank#27326637022

Activation: Even with a long-term subscription, sometimes reactivation helps. In Word, go to Help > Activate Product (or sign out/in via Account menu). If preferences are grayed out, this might be related. this was mentioned in a similar post: https://learn.microsoft.com/en-us/answers/questions/5421407/keyboard-wont-work-for-word-on-a-mac
Reinstall Word: As a last resort, uninstall via the App Store or Microsoft site, then reinstall from your 365 account.
If these don't resolve it, please comment and provide more details like your macOS version, Word version and whether this happens in new/existing documents or both.
