League of Legends has its fair share of error codes. One of these is simply known as 0 &an error that usually occurs when using PBE client. In most cases, the bug causes the home screen or tabs in the client to not display correctly.
Although I reported the bug Riot support should be your first stop to solve the problem in future cases, you can also install Hextech repair tool. This internal tool allows you to read and fix all game errors, which are then sent back to Riot Games for further analysis.
