Steam Client Stuck on 'Loading User Data'? Yeah, That Happens Sometimes

Many users found their Steam clients stuck on the "Loading user data…" screen after logging in, though Steam itself was not down and remained accessible through a browser. Some users reported that removing a game demo from the licenses page in a browser could fix it, but the workaround did not work for everyone. The issue is not new, with reports from a week ago and even years ago, and the most reliable fix is to wait for Valve to resolve it, usually within a few hours to a day.
