Issue with Variable Data in Photoshop – "Replacement file not found" error

Hi everyone, I'm trying to use variable data in Photoshop to generate multiple cards, and I've successfully imported my Excel CSV file without any issues. The data appears correctly in the Data Sets under "Image > Variables > Data Sets." However, when I try to preview or apply a data set, I get the following error message: "Could not apply the data set because the replacement file was not found." All my variables are being read correctly, and the values show up in Photoshop's Data Sets panel. However, it seems like Photoshop isn't finding the linked files.
