When I want to restore it gives me this error – Manifest data not found in archive.

I got an issue with snapshot, I need to restore a site and I see this from the restore page:

Notice: Undefined index: MANIFEST in /var/www/html/wp-content/plugins/snapshot/lib/Snapshot/View/Metabox/Admin.php on line 1737

I am struggling to restore my site, it takes 2 seconds to restore 100%.

The server tweak we did also did not solve the issue.
