I'm working on this part and cannot seem to get it to unbend. I've suppressed many of my features and have no broken features. What causes a part not to be able to be unbent?
There can be many reasons that can cause a model not to unfold. Attach the model, your picture doesn't give enough information to determine a cause.
Attach your part.
Drag roll-up bar below 2nd feature does it Flat Pattern?
Yes, proceed to next feature.
No, back to school.
Thank you all for getting back to me, I have attached my part as you requested.
Are there any unresolved issues indicated in yellow highlighted triangles in the feature tree?
Is Sketch11 fully defined with no extraneous geometry?
Does Ctrl Q return any errors?
What does Cut-Extrude2 actually cut? OK, I see it, but I get an error for the sketch.
Is Fillet 2 a legitimate technique for crossing a Bend - or should have Unfold/Refold been used?
Are all Edge-Flange consumed sketches fully defined?
Are you going to rip Edge Flange12 in the real world?
The technique that I used to diagnose - drag the roll-up bar below second feature and Unfold - Collect all Bends.
Repeat each step down the feature tree.
So, Cut-Extrude 2 creates a hole on left corner of Flange-2 and none of my features are highlighted with yellow triangles. Sketch11 is fully defined and Ctrl Q doesn't return any errors.

Did you Attach the correct file here?
This is what I see
Yes, I updated this sketch so that it is fully defined.
This will be cut on a flatbed cnc machine and will be bent into shape.

No clearance on sides for Edge-Flange12
The issue seems to be with 'Edge-Flange9' - if you simply add a slight offset (0.0005") to the flange it will unfold as it should. Solidworks at times can be finicky when it comes to even the slightest material interference in the bend region.
I am working with Solidworks 2016, would you be able to save the file in an older format so that I can open it?
Sorry Andrew, can't back save.
This is the slight change that you would need to make to have your part unfold.
