Window was stuck and when I went to force it with the crank, something broke/sheared. The two pieces were loose and came out of the unit with zero resistance. Threads on circular piece looks sheared on 2 sides, not sure if it should look like that.
(Please ignore the disgusting mold on window. It is in shower and above eye-level and I didn't know how gross it was until getting on a ladder to take a closer look!)
