Convert Multisite to Single Site

Have a multisite, looking to convert the existing multisite to single site, where I’m looking to make the blog ID 2 to load as single site once done.

Trying to make it work via Snapshot plugin, by taking snapshot of the subsite ID 2, and move it into single WP site. But the backup process is stuck at 1%, and not making any progress.

Please check chat transcript for more info, and advise what would be a viable solution regarding this.
