BLZBNTAGT00000BB8 Cannot update, repair, or play game

Any chance of any help with this Blizzard? The workaround that was working for me is no longer working.

I have reinstalled WoW, I have reinstalled Battle.net app many, many times. I am running as administrator. I have checked all permissions. I have disabled anti-virus. When I do manage to get on, my game plays fine, in other words, there is nothing wrong with my game installation.

This is happening completely randomly. After following support’s instructions in another older post - COD Warzone: Scan and Repair loop / BLZBNTAGT00000BB8 Errors - #5 by PyR0-11237 - I’ve been able to play with no issues for the last 2 days. But today we’re back where we started again.

What I’ve found is that any workaround might last for 1 or 2 log in attempts, and then stops working.

Just a reminder, this is a paid service, so it would be fantastic to get some assistance here. Currently I’m paying for a game that’s averaging half an hour of my time every time I try to log onto it. The fact that no-one from support has even responded to this post is not exactly making myself or the other ~20 people in this thread alone having the same issue feel like valued customers.
