League - Critical error has occurred, process must be terminated error

Every time I get past champ select/ban and the game is meant to go into the loading screen, it comes up with the error in the title. Can anybody help me fix this? I've even uninstalled and re-installed and it still has the issue.

We're testing a new feature that gives the option to view discussion comments in chronological order. Some testers have pointed out situations in which they feel a linear view could be helpful, so we'd like see how you guys make use of it.
