Error reading layout file - Can not unzip

I am having an issue opening my layout file. I keep receiving an error message saying "error reading file .layout - file pathway. I have been unable to unzip the file as per other similar issues.

Can someone please assist with this issue.

Backup of Backup of Interior Concepts - REV A.layout

The Layout file you uploaded ends abruptly and therefore does not contain several files that are essential. Do you have any other backups?
