Recently, I downloaded Dropbox to try it out, and upon realizing it required a subscription after 2 GB, I decided to cut to the chase and delete it. After syncing everything, I followed the instructions found here.

However, after deleting it, I realized my Desktop, Documents, and Downloads folder, the same folders Dropbox synced were "missing". They were still there, but the original icon was gone (the arrow pointing down for Downloads, for example), and upon clicking them, they showed: "The operation can’t be completed because the original item for “Downloads” can’t be found."

I've tried re-launching Finder, restarting my computer, to no avail. I tried this, but found that my iCloud was not synced, and every other search result was something along the lines of "Deleting files in dropbox deletes them in mac as well". I opened the "Macintosh HD/Users/[username]" folder, and found that where documents, desktop, and downloads used to be, there were aliases:

Upon clicking these, it showed the same error as before: "The operation can’t be completed because the original item for “Downloads” can’t be found."

I went to my Trash, found the Dropbox folder, but found it empty. No "Mac" thing in it. I could try dragging the documents, downloads, and desktop folders into the sidebar, but I would like my three most important folders to not be in the trash, and for aesthetic reasons, to have the old icon back.

Any help is appreciated.
