The last time I used Illustrator, it was the version previous to 2021. I was able to import and export workspaces from the Workspaces menu in that version. Now I've got Illustrator 2021, and I can't find a way to import a workspace from the Workspaces menu or the preferences, and I can't find anything online that says that others have had the same problem. I also tried copying the .exec file of my custom workspace into the folder with the rest of the workspaces, but it seems to be a different file type than the pre-installed ones, and it's not showing up in the Illustrator application.
Does anyone know what might be wrong, or what I can do?
