Suddendly only Empty Frames in Print Module
Dear Community,
Suddently the print module only shows empty frames.
Print with 18 custom pages with own layouts.
No library filter activated! Photos are in a print collection and shown in the strip. The photos can still be found e.g directory not moved.
Two days ago right before I closed Lightroom Classic, the photos were still shown, today I opened Lightroom Classic and only empty frames appeared.
I had been using this particular collection and page set-up for several months without issues.,..until today.
I also tried to restart the app and also the computer.

Remark: I added some grey frames over the personal data.
Is there at least a workaround to show the filename that was used for each of the empty frames. This would make it easier to restore the print album.
Mac Ventura 13.4
Lightroom Classic 12.3
M1 Macbook Pro 32gb
I would be glad for some help since a lot of effort went into creating the print view for an album.
Thank you and best regards,
Chris
