There is a problem when trying to combine large numbers of files to a PDF using Acrobat, it will sometimes break, and claims all JPEG files are unreadable (but selecting a smaller selection of the same files works). Then at the end it says "No PDF file was created because Adobe Acrobat encountered an unidentified error.

Yet again I am having to switch to using rival software to do a job that Acrobat should be doing right.

Latest version of Acrobat Pro from Adobe Creative Cloud, Windows 11.
