Scanning for Game Files

I click update for Overwatch and it instantly insists on scanning the game files, if it is allowed to scan for the game files it results in an error code. I have uninstalled Overwatch and reinstalled it, I have uninstalled both Overwatch and the launcher and reinstalled both, set both the launcher and Overwatch to run as admin, disable any anti-virus (in my case only Windows Defender), and I didn’t have any proxies enabled to begin with so no need to disable one. This BLAZBNTAGT error code is an old problem, doing a quick Google search I found an old WoW forum post from 2014 with the same problems, the only fix so far is to uninstall Overwatch and Battlenet and stop playing entirely. Are there any fixes for this whatsoever?
