There are two ways I can think of that lead to a SKP showing as Embedded. One is where you copy and pasted geometry from SketchUp straight to the LayOut page, the other is where at some point the SKP was missing, and you relinked it to the copy in the working folder.
The one that is embedded is named 1455410760_Lee 1.04_197.skp. I copied that out to a normal location, renamed it to Lee 1.04_197.skp, and relinked it. That then looked more normal.
But, it didn’t stop the crashing from happening. The crash only happens in Windows, and does happen with the latest version of LayOut that I have. I will check to make sure there is a bug report about that.
As an aside, I think that in recent versions the bugsplat doesn’t happen when you crash, but shows up when you next open LayOut or SketchUp. In this case though it’s crashing in a way that you don’t see one even then, and also note how the file you had open is not in the recent files list.
Some amount of deleting of things later, the crash happens if there is only the Default layer and the Model view 1 layers left, and only if both are visible. If either is hidden, the crash doesn’t happen.
I will try to find exactly which elements are causing the problem.
