My VRChat world appears as a 'Fallback' world. How can I fix it?

A 'Fallback' world appearance means the intended world failed to load correctly. Common causes include missing or corrupted world data, incompatible VRChat client version, or issues with your network connection. Ensure your VRChat client is up to date, verify game file integrity via Steam, and consider clearing your cache and restarting VRChat. If the problem persists, the world creator may need to update the world itself.
