Couldn't click/move/alt+tab/alt+f4 in game.

So just encountered a bug where I couldn't alt+tab, alt+f4, only thing I could do was hard reset of my PC and even though I reconnected after the hard reset of PC the bug was still there... Free lose in my promo's because of it. Please get this bug fixed, before it ruins someones account.

Heard about the discord thing, didn't help uninstalling it. Also some ?directx? pop-up showed up (saw it being reported here as well), even though I have all my drivers updated daily.
