Losing my site files

Hello everyone!

I recently updated CyberPanel, and after the update, I was surprised to find that the files on one of my WordPress-based sites were lost or deleted. The problem is that one of my sites’ files were deleted, while the rest of the sites were still intact.
I checked that the database file on phpmyadmin was still there.

I don’t have a backup.

I don’t know why this happened, because every time I update, this never happens to me.

Is there any hope of recovering the site files, as they are very important to my work?
Perhaps there is a place or something where I can find my files?

update is not deleting anything there must be something else. Can you check all access logs?
