@Inculpatus cedo.9234 tried to message you but you can't receive messages so here goes.
Not sure if it was you using the confused Icon on my post, I was trying to let them know there is a know issue going on since SAB was released a week and a half ago. I too tried everything including repair to see about the slow and partial load screens, so I added a link to the current conversation about that.
Not meaning to draw a comment just trying to help the OP.
Thanks!!
