Repro Steps:

1) Create a Page
2) Open the attached NoesisTechnologies_NoBG.ai in Adobe Illustrator, select all of the contents on the page, and [Ctrl+C] to copy them to the clipboard.
3) Open Studio, and in the RootGrid of the Page that was created in Step 1), paste the paths copied from Illustrator using [Ctrl+V]. This will create a Canvas element containing all of the copied Paths.
4) In the Navigator, expand the automatically-created Canvas.
5) Select any Path inside of the Canvas, and click-and-drag it to move it from outside of the Canvas, into the RootGrid.

Observe Studio crashing.

Expected Results: Paths can be moved throughout Navigator layers without issue/without crashing.
