Acrobat PDF File Format error when saving .AI documents. The size of the passed callbacks struct is wrong.
Illustrator 30.0 (64 bit.) windows 11 recently loaded then I updated to 30.0. since then 99 % of the time I open my current .AI files to update them and save them, I receive this error which I can't fix. The only way to bypass it is the save to the downloads folder and then over write the original unsaved file with the new version. This is affecting my production time, so it is quite urgent. It could be a setting but as I don't understand the message I can't fix it.
