I'm glad using the archive file worked, thanks for the update.
From what I can tell, it looks like Fusion is trying to open the design from a crash recovery direct and failing. I suspect because there is an issue with the recovery file.

At this time, I'm not sure how to reproduce the issue from scratch, but if you have any suggestions or ideas, please let me know.
Either way, I'm happy you're able to move forward with the archive file.
Thanks again!
