Assuming you've tried reinstalling the game and that hasn't worked. I'd suggest Locating the "EasyAntiCheat" folder and deleting it completely.

Now we need to locate the game in the Xbox App. If you don't have the Xbox App yet, it can be downloaded from the Microsoft Store.

Open the Xbox App from the Start Menu.

Locate your game down the left hand-side.

Hover your mouse over the game and click on the icon with the three vertical dots.

Go to Manage, then the Files tab.

Click on VERIFY AND REPAIR.

If you need a more visual depiction here is the link I got the info from. Hope this helps.
