Hi Chris, thanks for responding.
Yes, the CSV was generated by CAMELOT. The problem is as follows: I was working with a dataset stored on an external hard drive, and everything was working correctly. However, after disconnecting the hard drive a few days ago and reconnecting it later, I was no longer able to access or work with that database. It seems the system no longer recognizes the directory paths where the information was originally stored.
Luckily, I had already downloaded the full export CSV, which contains all the photo information I had processed up to that point. As a workaround, I tried performing a bulk import with this CSV, but ran into the issue I mentioned earlier.
