[Crash] Kalistra soulbond crashed my game

Playing as Garen on murder bridge. I made it to the bushes, had a brief engage with the enemy Karthas. Then Kalistra came to the area and soulbonded me. The game acted as if it was lagging at first. Couldn't move, couldn't chat. I tried to exit and restart, and now I cannot rejoin the game. I keep getting a message saying "The game has crashed. Please reconnect to the game."

Not sure how helpful this is, or if Soulbond actually had anything to do with it. But, I've had no issues until this game.
