Crash when clicking inventory and then clicking game.

played for 120 hours or so with zero problems until today.

Whenever I click on my inventory (or click around in the menu) and then click the game rather than hitting esc to close the menu... the game crashes.

also if I click on my browser and then click back on the game the game crashes...

I have tried reinstalling... deleting shader cache... verifying... fullscreen/window/fullscreenwindow... different renderers... disabling steam overlay...

if anbyone has any ideas or is having the same problem let me know!

OK so I have narrowed it down a bit... it happens when I use my wand skill (Power Siphon) from any menu including my inventory...

when i switch to my melee character it doesen't happen... when I unbind power Siphon it doesn't happen
