Steam Client Loading User Data Error: How to Fix [Guide]

The Steam desktop client is freezing on the loading user data screen during startup on October 26, 2026, preventing PC gamers worldwide from launching their library titles due to intermittent Valve account authorization server sync failures. According to verified reports from Kotaku, the issue stems from background credential handshakes rather than complete server outages, leaving the web browser interface and mobile authentication services fully operational. Community members on Reddit identified a temporary workaround that involves logging into Steam via a standard web browser, navigating to the account licenses page, and manually revoking free demo or promotional sub-licenses to clear cached session profiles. While Kotaku verified that removing stale licenses resolves the boot loop for some users, Valve server-side resolution remains the only definitive fix. Client lockups of this nature typically self-correct once regional infrastructure clears authentication queues, but the sudden freeze disrupted weekend play sessions and scheduled scrims.
