Rename failing with large number of images and duplicate names

Lightroom Classic V13.2.

Windows 11.  Intel Core i7. 16GB RAM.


I'm attempting to rename a large batch of images using data from a csv file. I'm using the LR/Transporter plugin to import the relevant field (barcode) from the csv file into the image metadata (in this case the Headline metadata field). There is no problem with this step. Then I've set up a custom rename preset that renames the images to the Headline value, but this fails for a large number of the images (see attached screenshot). There are multiple duplicate values in the barcode field (see attached csv file). When I trialed this workflow with a small number of images, including duplicated barcode numbers, it worked without a problem. However my workflow involves processing around 2500 images a day so I need this to work with large numbers of images. I suspect it has something to do with how Lightroom handles the duplicate barcode values, possibly not being able to keep track of a large number of duplicate names while renaming. I'll find a workaround the meantime but it might be worth finding out what the problem is. 


Steps to reproduce:

- create a directory with a large number of images (~2000),

- create a spreadsheet with two columns, filename and barcode. Add the file names for the images in the first, and add a set of barcodes with duplicate values (use from attached csv if necessary).

- use LR/Transporter to import the barcode values into the Headline tag of the images.

- try to rename these images to the headline (no other values) in Lightroom. 


Expected result: all images renamed correctly

Actual result: only some images renamed, others not, with the message in the attached screenshot.
