Client Crashes/Vanishes when attempting to open Crafting

Like 80% of the time i try to open the crafting tab to do some crafting and what not my league just closes its self and the little info bubble defining the tab remains. When I reopen league i get the prompt saying league is already running would you like to terminate and start a new one. Am i alone in this? I've repaired my client twice in the past 3 weeks and still run into this problem.
