On a Mac using Adobe Acrobat, updated to Version 2025.001.20997, I have encountered a recurring issue with using an image to add a signature on PDFs.

I receive an error message saying the JPG file is corrupt, though the file does not otherwise seem to be corrupt (i.e., with other applications).

I believe this is a bug because I can get around the issue by uninstalling and then re-installing the Adobe Acrobat app using Creative Cloud.

This is not an issue when I am using Adobe Acrobat on a PC.
