Error BLZBNTAGT00001398 when attempting to launch a game

When attempting to launch a game via battlenet I am met with a window stating an internal error occured (BLZBNTAGT00001398). I tried everything even uninstalling battlenet completely. After the reinstall the same error was shown.

Did you delete the folder they recommend to remove in the support doc?

Good afternoon.

I’m having the same issue, except the file in question i am unable to delete. Even in safe mode.

It is a Diablo 4 data file and it’s acting suspiciously like a virus. I don’t know what to do, but I cannot play the game I paid for unfortunately.

Everything was fine, then my game crashed
then this.
