That looks like a bit of a hollow wall fixing, you can see some barbs as if it has been hammered in. ...small screen though!

looks like one of those fixings that will take a bolt - try and see if an M6 or M8 fit, if so tighten a lock nut on it and it may wind back out.

Cut board above and below and rest should lever out easily with wrecking bar or similar .
