Need Help with “Failed to Open Document” Error

Hi,
I’m trying to open my file but I keep getting the message: “Failed to open document.”
I also tried converting the file format from .skb to .skp, but unfortunately, that didn’t solve the issue.
If anyone could help me open the file, I would really appreciate it.

Thanks in advance!

About 1/4 of the file is filled with zeros. Do you have the SKB backup copy of the model?
