Is this a job for a crowbar?
I would say no don’t use a crowbar unless you are good at repairing/ replacing
brick work. I would grind the head off that or burn it off with a oxy-acetylene torch.
I have put anchors up and use a torch to make it look like a rivet. In doing this it makes the bolt impossible to pull without cutting the head off.
Expanding anchors are usually used so pulling may blow the bricks out then removal and replacement will be needed.
Those look like drive in anchors notice the pin in the center. Again grinding or cutting the head off is the only way to do it without the possibility of blowing the bricks out.
