I just updated my illustrator from 2020 (v24.3) to 2021 version, and as I did that changed my language from Korean to English as well. When I opened a file i was working on with 2020 (has both vector & image) on 2021 version, it said that "illustrator could partially read this file" and actually nothing appeared on the workspace when it opened.
Also, when I tried placing an image, png jpeg by dragging and dropping onto the workspace, literally nothing happens. when I file > place an image i get this message :
illustrator could not read the file try replacing this with another valid link.
Ive been searching for solution to this for the last 30 minutes and couldnt find ANYTHING related to this. would really appreciate some help
