I agree.Is that your broken stud extractor off-centre in the sheared stud? The next size up would have been a good idea, and on the centre of the stud, but too late now. Also looks circular, I guess its the left hand threaded carrot type? So harder to remove than the tapered square type.
Because it's off centre you've got room to attack the remaining stud with a Dremel. You could even start by drilling a small hole or two. You might then be able to grind enough stud away to get a grip on the broken extractor, maybe tap it with a centre punch to loosen it.
I had not realised that the depression is the remains of the stud extractor but thought that was just an off-centre drilling. It is too small for that size of stud although easy-outs are notoriously unreliable and, after failures of my own even using the correct size, I now always reverse drill out and re-tap. That being the case, I would drill out from alongside the broken extractor and try and undercut it.
