[CRASH] Clicking shop button minimizes game

Pretty much just as the title says. I exited the loading screen, and when I went to click on the shop button, my game minimized. Going back into the game didn't help either, every time I clicked the shop button the game would minimize again. When the cursor is just floating above the button, the custom cursor LoL uses (the golden gauntlet) is replaced with the windows system cursor, but everywhere else on the screen the custom cursor was present.

Exiting out the game and then reconnecting, and reloading, fixed the issue.
