Missing photos after Big Sur update
I recently upgraded to the new OS, Big Sur (on MacBook Pro early-2015). There was a slight disruption when doing so and this may had lead to my photos disappearing, or not since I saw there were other problems with the update. Regardless, when I went to the Photos app it was completely empty. No photos appear on "Import" or "Recently Deleted". I did not have the photos uploading to iCloud nor did I have Time Machine setup. I am just wondering what I could do to recover these photos. I tried the Recovery option on the Photos app, but it didn't bring up anything. I also tried the Spotlight search and it only had the current library. Also in the "Show Packaged Contents" the "Original" and "Master" folders were empty.
Is there an imprint of them on the hard drive or are there other steps? I am quite desperate.
MacBook Pro 13″, macOS 11.1
