Have you reported to the mod author as well?

Looked like it was on your end based on the crash log, but I'm far from an expert. Added to their issue tracker as well.

@OreCruncher This is definitely an issue on our end that may have been fixed in the alpha-preview6 release made a day or two ago. Please feel free to close the issue.
