Broken casement window track guide

When opening this casement window I heard a snap noise and found that the bottom hinge portion of the sash is no longer sliding within what I am guessing is the track (see red boxes on image 1). Looking at the operator I was able to guess that its a Truth 31850 model (image 2) if that matters in this situation. I also looked at the window opposite to it which is functional and was able to identify the black plastic part that broke (green box in image 3). Is it possible to just replace this plastic piece or will the replacement be more involved?

Thanks!

I completely forgot about this post honestly, ive gone back to measure the track on the hinge set currently on the window, it measures approximately 9 and a half inches. Can I still use a 10" replacement hinge? Ive looked several places and it seems that 10 inch is fairly standard where as 9 and a half is not.

Thanks!
