Window not able to close to lock

Question

I have a window crank that works fine once the window is partly open, but is not able to close to lock or open once unlocked.
From the inside window cranks from left and swings open on the right.
How do you measure the length of the crank?

There is more that goes into identifying an operator than just measuring the length of the arm. I can do most of the work for you, but I'll need you to remove this operator from the window and show me a clear picture of the mechanism by itself and without obstruction. Please make sure it's one clear shot taken from the top-down.

With that, I am very confident that I can find a good match in our inventory. If dimensions become an issue, then we can cross that bridge when we get there.
