Data merge not working even though paths are correct

I have been data merging images and text for over two years at my job for a deliverable that we do a few times a year with no issues. Our Adobe logins recently changed where we no longer have Adobe Enterprise and got our licenses through TechSoup as we are a nonprofit. I used the same login (email) and use a different profile to access my Adobe license for all programs. My colleagues have done the same. When I try to data merge now, it does not work, whereas it did before. It only merges the text, and not images. It gives me the message that says:

"The data source references one or more missing images. The missing images cannot be previewed or merged. At the time you create a merged document, you can choose to generate a list of all missing images."

I am on Mac and have checked the platform style path and am using the right file path/source (for my computer username and links). No matter what I do it does not work for merging images when it worked over a month ago on the old profile that no longer has the Adobe license. I had my colleague check and in the copy of the .csv, all she did was change the username in the paths to be her computer name, and when doing the merge, it worked for both text and images. My supervisor also did it on his computer with a copy of the .csv with his computer username in the paths and it worked as well.

I am not sure why it is not working for me in regards to images. Is there something I'm missing/not checking? I copy/paste directly everything for the sheet and file paths so there's no misspellings or extra spaces, so I am at a loss as to why it won't work for me, but works for my colleagues. Any help would be greatly appreciated!
