Adobe Illustrator could not open the PDF file
Hi there, I have been working on my Illustrator for a project for over two weeks, which I have saved as PDF, compatible with Illustrator. It was all right as always for the past two weeks opening, working, closing, and saving without a problem, but it suddenly said that it could not be opened in my Adobe Illustrator today. I have no AI file for this project and only a PDF file saved in my Google Drive and computer, but both can't be opened. My Illustrator version is Adobe Illustrator 2022 v26.0.3.778 (x64) Multilingual. It would be a great pleasure if anyone knows of any way that can help. Thank you.
