In Bitrix, when editing in the visual editor, a component disappeared, how to return it?

Question

1C-Bitrix

Good afternoon. Tell a newbie. In Bitrix, site management in the visual editor, where you can select blocks directly on the site, opened the component template, did not change anything, accidentally clicked "save" - ​​the entire component disappeared on all pages. Since it was a directory section, now it gives out a 404 instead of a component. How can I restore it? There are no backups. Thank you.
