System Error, Created a Dump File

Hello i had some difficulties with League of Legends when i was playing some urf my game crashes after 2-3 minutes of the match then a window appeared saying "A critical error has occurred and the process must be terminated would you like to create a crash dump to aid the developers in troubleshooting this issue? this may take up to 5 minutes NOTE: The process may appear unresponsive during this time" i created a crash dump so i hope it helps and that it doesn't happen again.
