While playing League of Legends you may occasionally run into an issue that causes your game to unexpectedly close. When this happens BugSplat informs you that your program has run into an error and needs to shut down.
We know that crashes are not fun - using this document will help you get back to playing League as quickly as possible.
The first thing to do when you get a BugSplat error is to submit the report. To do this, document what happened before your crash and hit 'Send Error Report'.
This might seem like a pain, but getting a short description about what caused your crash is a really helpful tool for developers when fixing the problem behind your error.
After submitting your crash report you may not see this error again.
If your issue persists then you should visit Riot's support forum to get help getting back to playing LoL.
Some common problems involve minimum system requirements, out of date operating systems, corrupt game files, and incorrect game settings.
If none of the suggestions on Riot support forum fix your problem then you should submit a ticket to Riot support.
