Mac Photos Import Unrecognizable File Format

I’m pretty sure most of these files will import successfully if done in very small batches. I have thousands of photos & that’d take a year. Maybe there’s some way to isolate these “unrecognizable files” & move all the successfully imported ones into another folder? An Automator script perhaps? I know lots of folks are dealing with this problem, so just wondering how it’s being solved .. or at least worked around for those in the same situation. https://preview.redd.it/r8qnyvu2jj6e1.png?width=660&format=png&auto=webp&s=459c51c5d7198a57f2b9cc4a1e460f07e5574027   Thank you https://preview.redd.it/4yt8cyz1jj6e1.png?width=468&format=png&auto=webp&s=88ee14e0e22af20a4e7f4fa02cb420a577bb6cdc
