As a result, they are simply unable to play the game, which can be extremely annoying to many. Due to this, many users started asking about how to deal with LOL patch kernel not working.[ref en-2]

League of Legends is the most popular MOBA (Multiplayer Online Battle Arena) game in its genre.

Those who experience the issue can see the following error message on their screen as the game fails to launch:

Close the program
