Did you create this or someone else? Someone may have had an ESKO plug in or similar that you need installed to open the file. You migth be able to open the PDF half in Acroant, then save as PDF and open in Illustrator. Be careful as plug in  items like UPC code  might drop or other.

Thank you very much ... Actually I was using Illustrator 2019 but after updated my mac OS to latest version, my Illustrator got crashed and couldn't open any existing ai files. So that I updated my Illustrator 2020 as well and then I tried to open my ai files in 2020 version but I got this error msg.

Now my problem is solved. I moved the entire project folder includig ai files folder to desktop and all ai files are now working properly.
