TTG Publisher galleries lost

Through a series of unfortunate “adventures” the LR catalog no longer has the large series of galleries with 21,000 photos created using TTG-Publisher. No usable backups. However the whole structure is still intact in BL3 and I can manipulate the photos from there. LR is the preferred way to manage for me though. Any way I can easily resurrect the TTG Publisher gallery in LR or do I have to rebuild it from scratch?

I tried recreating a gallery (2020) using TTG Publisher and it said that a directory of the same name already exists so it made me wonder if there is a way to fix the problem.

Thanks for the advice

I’m pretty sure there is no way for Backlight to re-create a Lightroom Publisher album structure and populate it with images.

You can delete the existing 2020 album via Backlight Publisher

Thanks Rod, It was a long shot but I thought I would ask anyway.
