What is skyui error code 1?

As an AI language model, I don't have access to a specific error code 1 in SKYUI. However, generally speaking, error codes in SKYUI can occur due to various reasons, including corrupted or missing files, mod conflicts, outdated SKYUI version, incorrect installation, and others. The best way to resolve an error code in SKYUI is to consult the mod's documentation or forums, verify the load order and compatibility with other mods, and try reinstalling the mod. In some cases, it may be necessary to start a new game or revert to an earlier save. It's also recommended to use a mod manager and create regular backups to minimize the risk of errors and data loss.
