Can't launch Hearthstone from Battlenet desktop app

Just updated Hearthstone, launching it returns an error which states as follows.

Failed to initialize player

Failed to load PlayerSettings (internal index #0).
Most likely data file is corrupted, or built with mismatching
editor and platform support versions.

Kind of odd, because Hearthstone ran fine last time I was on my PC. (like a week before the update) and I haven’t touched it since? Any information on why this is happening and advice on what to do next would be appreciated.

Hey, Dazork04! This error is a unity engine error when its out of date. Hearthstone utilizes the Unity engine. Have you tried reinstalling the game to update the game client and unity engine?
