If you have installed Microsoft 365 on your PC, click your Start Button, then just type Word, does Word appear in the resulting list and if so, are you able to open Word from there?
If not, if you are using a WIndows device, open the Settings App, go to Apps - Installed Apps, scroll down, do you find Microsoft 365 in the list of installed apps?
