[CRASH] Ingame shop crash when trying to buy items

Since 5.15 patch my game will crash whenever I hover over or select certain items in the ingame shop. It happens about 70% of the time. It is most prevalent in ARAMS when I'm trying to shop after death. Sometimes just moving my mouse over an item will give me the bugsplat screen.

Im on Win7, latest drivers.

This never happened before ever....
