You should restore your old Lightroom Catalog backup and that should be containing all your images and the edits that you have done so far however, it might show the images as missing which can be relocated.
Follow the steps mentioned in this article to relocate the missing images once the catalog is restored : How to find missing photos in Photoshop Lightroom
Thanks a lot. Have a Merry Christmas.
Merry Christmas to you too
I have a similar situation and im trying to "open catalog" from my backup files, but when I do, there's a message:
Lightroom cannot use the catalog named "LightroomCatalog.lrat" because it is not writable and cannot be opened.
This could be caused by incorrect permissions or because another Lightroom application is using catalog. You may try to correct the problem or you may select a different catalog.
Any idea how I can get my backed up catalog(s) restored?
Check the permissions for the folder containing the catalog and ensure that the folder has both read and write permissions.
