Lightroom Classics 13.1 Skips some files during export

Hi! I have Lightroom Classic 13.1 on Windows 11. When I try to do a batch export selecting all the 46 images that I edited only 9 of them are processed. The output folder contains only 9 of all the 46 images that I tried to export once Lightroom finished the process. No erro rmessages. If I export the same images one by one it works correctly and all the images are in the output folder without any issues.

Anyone has solutions? I use lightroom from years and never have this problem before.

Thanks,

Rodolfo
