[CRASH] Game Crashing Seemingly Randomly

Whilst playing a league of legends game as Caitlyn, my game kept crashing every 5 minutes. In the 30 minute game, my game crashed over 7 times. The bug occurred in my last game whilst playing in patch 7.13 on a mac. Unlike normal disconnects, my character also stood still until I reconnected causing myself to die as well. Nothing seemed to trigger the bug but I was playing against a Jinx/Braum bot lane and with a bard if that might be causing it. Sorry for the lack of detail and vagueness of this discussion, I am still quite confused as to why my game kept crashing. [edit] After running some more tests, I have found that this crash is all but random, crashing during bot games, during customs and with other champions. It sometimes happens when buying items, getting kills, moving, pinging, basically anything.
