Looks like the gear bore came out, which means you'll need to replace the whole operator, not the handle. I can help you find a match, but I will need to see a picture of the operator removed from the window. Alternatively, you can open the window as far as it can go and show me the arms. Either way, I'll need to see the design of the arms before I can offer a replacement. Thanks!
A home owner from edison ,NJ says:
Do you want me to send photo of the arm with fully open window, it might take few days when weather improves for me to open window. I am not sure if I can remove operator from window let me know if any suggestions.

Whichever way you're more comfortable with! We just need to see the entire operator. See the video below for help on replacement.

Thank you. Please see our 39-031 and 39-032 and see if these will work. All you need to do is confirm that the dimensions are the same.

To replace this operator, you will first need to remove the vinyl sill cover that goes on top of it.

There has to be away to access the mounting screws in the base of the operator. Take a good look and see if you can use an off-set screw driver to access the mounting screws. If you still can't get to the screws, you have to remove the sill cover. There is no other way.

Looking at your first photo you sent, it looks like there is a seam on the bottom of the sill cover. That mean it might be one that snaps in place. Take a small screw driver or chisel and try to pry it up at one end and see if you have any luck, just like how we show in our video. You just have to be more careful that you don't crack or damage the plastic on the frame. If you are not comfortable doing this then I recommend hiring a handy person to come out and do it for you.
