Icons of app on laptop disappear. Apps can t be opened. What to do

I can't open Outlook anymore. Actually, I accepted that and used another mail app. But now it's the same for a game. What should I do? I have a Lenovo laptop with the latest version of Windows 10.

Is that only in Outlook or the other Office programs?

Only in Outlook and now a few months later in a game by EA

Have you ever tried to fix the Office installation?
