I updated Illustrator to version 24.1.1 3 days ago. I've opened some files to discover that the most recent changes I made to them have been deleted and the version of the files are about a week old. I know I saved these files with new changes but those changes are no longer there. Is it possible to fix this bug and restore the previous files from before the update? I don't know what in the update triggered deleting these new changes.
