Hi,
Is there any way to get it back?
In easy way, no. But your hosting support should have database backup from day before you made "bad" click.
Then open database file (backup) in Text editor and find that page , search by its name. That page should be in prefix_sppagebuilder table. Then use PHPMyAdmin (in cPanel) and find the same page on current database, and replace content, and save changes.
Longer way - recover page from recovered backup, export-import.
I shared only basic tips, whole rest is in your hands. Every action has its consequence.
