One scenario where Steam’s cloud error appears is if you’re using Steam on a new device where you’re logged in to your Steam account but haven’t enabled cloud sync. This confuses the app about what game progress file to load for your game.

In this case, enable cloud sync in your Steam client, and your issue will be resolved.

Open Steam on your new device.
Select Steam in the menu bar and choose Settings.

Check Your Game Files’ Integrity
Your Steam game library may have gone corrupt, causing the client to display an error message. Various items, like a virus or a malicious app, can cause your library to become corrupt.
