Crashing when selecting BrepFace using createNewFaceContourSelection() on a setupInput Object

Fusion is crashing when I select BrepFaces for boundaries on the setupInput object, but not when I select a sketch object.

As a work around, you can select all the edges of the face and use the .createNewChainSelection() method. This works as expected.

We have logged an issue FUS-173100 for it & we are looking for the solution .

This also occurs with the createNewSilhouetteSelection() method, just in case that is not mentioned in FUS-173100
