[Client] Game interface disappears after clicking hextech button

OS: Windows 7 Client Version: 0.49.0.214 Game version: 6.15.16_07_21_02_05

Bug: Game client interface disappears after I click the "Loot and crafting inventory" button.

Steps to reproduce: After finishing a match (doesn't seem to matter what type of match - happened on SR, ARAM, and most recently One For All) where I receive a chest or key fragment, I click "Home" at the end game stats screen, then I click "Loot and crafting inventory". As soon as I hit the crafting button, my entire game client disappears except for the hover text for the button I pressed. Pressing other buttons works fine and does not crash the client. Game client is still running according to task manager, the interface (minus the hover text) just completely disappears.
