Hello,
First, I would recommend looking in the Recycle Bin of your PC. On the desktop, double-click the Recycle Bin icon and look for any photos in there that pertain to the ones you looked at.
If you can't find them there, try using Recuva and see if that can recover your files.
If you can't find them afterwards, try using the Windows File Recovery to restore files. You will need another disk to be able to restore. Once installed, open a Command Prompt window as admin and then copy Winfr C: D: /regular /n %UserProfile%\Pictures\*.heic and push enter. Let the app try to restore the photos onto the new disk. Replace Pictures with a different file path (for subfolders, separate using the \ backslash character).
Please let me know how this goes, and if you have any questions, please do not hesitate to reach out!
