Broken Casement window operator

Question

I have a left hand crank operator of which I'm not sure who the manufacturer is. I can open the window but I can not close the window. The auger which meshes with the gears can be removed as you can see from the photos. I don't think this is the way it's supposed to be. There seems to be a small chip in the first auger gear when it's removed. The crank handle has a number on it. That number is 15 45054. The mechanism plate has a number on it. That number is 46197. I appreciate any expertise you can share with me. Thank you.

Hello there. When that worm gear pops out with the handle, I am afraid it means the entire operator is stripped and should be replaced. I am pretty confident we can help you do that, but can you open the window so I can get a clear view of the link arm(s) that connect the operator box to the window? From there I should be able to identify this for you. Thanks.
