Do you know why?

Hey @Paci
I found similar issues here:

Referring to the topics mentioned above, you should first ensure that the PDF file is properly saved. Try opening it to check whether the file is corrupted or not. If the file seems fine, you could also try removing package from UiPath and reinstalling it.
If the PDF was transferred via FTP, make sure you used binary mode for the transfer.
