How to Fix Error 62003 on InZOI

Struggling with error 62003 on InZOI? Don’t worry, you’re not the only one. This bug shows up pretty often, especially when you try to link your Steam account to your KRAFTON ID or claim rewards through Twitch or CHZZK. The result? You’re blocked, and the game shuts you out. Fortunately, there are several ways to fix it quickly so you can get back to playing in peace.

Most of the time, this error is linked to a connection or synchronization issue between accounts. Either your Steam account isn’t properly linked, your authentication token has expired, or a platform like Twitch needs to be reconnected. It used to also be caused by Denuvo, the anti-piracy system, but good news: it's been removed from the latest versions of the game.

So, how do you fix error 62003? First, go to the InZOI account management page or directly to the Drops event page. Make sure your Steam account is correctly linked to your KRAFTON ID, and check that everything is working with Twitch or CHZZK. If one of the platforms is acting up, disconnect and reconnect it manually.

If the issue is due to an expired token, reconnect everything from your KRAFTON ID page. Sometimes it works better through the mobile app than on PC, so try it on your phone to claim your drops.

Also, remember to update your graphics drivers. Outdated drivers can cause connection failures or weird errors. You can also check if your PC meets the game's requirements (VRAM, specs, etc.) with a site like Can You Run It.

Still bugging out? Steam might help. Right-click on InZOI in your library, go to Properties > Installed Files, and click Verify integrity of game files. Sometimes, one corrupted file is enough to mess everything up.

Last resort: uninstall the game’s demo and reinstall it cleanly. It’s a drastic move, but it resets everything and often fixes the issue.
