I cannot save large size (50x70 cm) PDF from Illustrator. Giant crosses are coming in the recorded document. Although the actual size of the document is 10%, the Acrobat application measures the size that is not but should be. If I make the PDF version in 1.6, the result does not change.
System: MacOS 12.6 TR,
Adobe latest versions TR
Installing the old version also did not fix the problem.
Looks like you are using a large canvas document.
Try to copy it into a regular sized new document.

I don't understand how it happened. But copying it to a new document just as well fixed it.
Good to hear that helped.
