If you're encountering this error, it should be just after you've tried to log in to League of Legends via the Riot Client. You'll get a popup with this confusingly obtuse error code, and then be forced to close the League of Legends client. This error is caused by Windows, so the problem is something on your end rather than with Riot. Unfortunately, Riot Games hasn't figured out any specific causes, so the solution is a solve-all approach.
- Launch League of Legends with administrator privileges, which can be done by right-clicking the program file and selecting the "run as administrator" option
- If this doesn't work, uninstall League of Legends via your OS' program manager
- Reinstall League of Legends from Riot Games' website
This error shouldn't persist once you've tried both of these solutions, particularly after you've created a fresh installation of League of Legends. If, by incredibly poor luck, you continue to receive the error code, it's best to file a support ticket directly with Riot Games. Error 0xc0000005 is one of the game's most obtuse errors, so solving it can be unfortunately finnicky.
That's everything we know about Error 0xc0000005 in League of Legends, its causes, and how to fix it. Hopefully, you're back to Summoner's Rift, Howling Abyss, and Arena in no time. Best of luck!
