I purchased the part jeffery suggested... only ~$5, so inexpensive yes. But, not the exact same part as i would need (too short) if that was the only problem. Because upon removing the black plastic knob which houses the crank extension thingy, it became apparent that the issue is further down in the mechanism itself. Though slightly stripped, the whole shaft does spin ok, but the torque arm is not getting engaged (I think?).
So to me it looks quite a bit more involved... something along the lines of:
There is also videos out there of people doing torque arm repairs but they are pulling the whole window out... again, much more than I want to do.
I need to research a bit more I suppose...
