Visual Glitch after downloading game after 6 months without playing

So basically I installed both blizzard. net and Hearthstone again after about 6 months of not playing. Everything seemed fine with downloading and everything and my computer has run hearthstone before. But now when i boot up the game it gives me this visual glitch where some parts are grayed out like the “quest button” and when i click on something like “solo adventures” a lot of the screen becomes black apart from a few things like portraits and stuff. Music is completely fine and it looks like I’m able to access everything, its just basically impossible to see. Would really appreciate some help with this

I am using a PC and i don’t have any apps with overlays
