As a last resort, if you cant pry or tap it up, maybe the smallest size e-z out could fit in there, they tighten counter clockwise. After you start it keep turning the wrench and pull up on the shaft of the ez out with needle nose plier or vise grips. it should come up. If the easy out goes thru it, it will drive against the part its wedged into and help bring it up. I dont have machine or ez out in front of me. sposed to b workin!
