[CRASH] League keeps closing out randomly

Every time I go to create a new game in draft pick normal and I go to click on the store or my profile to check something (while still in the lobby), my entire game will crash and close out. 8/10 times this happens and i have no idea what is going on. a few of my friends have experienced the same issues with their game crashing after clicking into the store while in a game lobby. Is there any way to fix this?
