How to Fix League of Legends Error Code 0U
League of Legends players, particularly those on the Public Beta Environment (PBE), have been encountering a persistent issue known as Error Code 0U. While this error can affect the main client, it’s more frequently reported by PBE testers.
This article explores the causes of Error Code 0U and provides potential solutions to help players and testers alike.
Understanding LoL Error Code 0U
Error Code 0U is an error that affects League of Legends PBE. When this error occurs, it prevents the game client from loading properly, resulting in various display problems and impeding access to important features.
The exact cause remains unclear, but it’s likely related to the game’s client structure, which runs two separate applications:
- One application controls the menu interface
- The other manages the game itself
This dual-application system can sometimes lead to conflicts, resulting in errors like 0U. The problem affects players worldwide, suggesting it’s not limited to a specific region or server.

While Riot Games works on a permanent fix, players can try the following solutions:
1. Use the Hextech Repair Tool
