My friend had the same issue and just re-installed league of legends and was a easy fix.
I've found a few of my folders being corrupted, just a few of them just now , so , I'm asking some favour from MPGH users out there who have GarenaLol folder(playing League of Legends in Garena ) to help me with this. Someone who is willing to help can kindly PMed me .
Best Regards,
