Enfold Theme Disappeared after WordPress Update

Hello,
I run a website for a large business. The original developer used Enfold. Years after his departure, I have been maintaining the website while still using Enfold. I can not get in touch with him.

Recently, WordPress had an update at the same time that my web hosting server went down. The c-panel was inaccessible for days. When it returned, my Enfold theme had disappeared completely. After multiple restores and failed backups, no one can seem to restore the theme to have a properly running site.
