Today I was working on a file (the file contained heavy graphics) in illustrator 2020. During work there were some problems. I was creating an isometric typography. So after work when I went to save the file as AI file a dialogue box appeared and showed " an unknown error occurred ". I tried more than 10 times. I even quit illustrator (without saving). When I opened it again the file disappeared!
Then I uninstalled Illustrator and reinstall it again. Will my problem get fixed and will I get my old files back?
