Any new catalog you create will be empty!. (Not the way to restore)
You need to locate a previous backup ZIP file of the catalog, extract the catalog file (.LRCAT) from the ZIP, and copy it to the folder location where your catalog normally resides. As described in this link- Catalog Backup Restore
You will not have data you have entered since that backup catalog was last saved, so will require some work to import and get the catalog up-to-date.
Frequent catalog backups are essential for this ‘corrupt’ scenario.
