I’m having the exact same issue! Tried several times, same thing?
Blew 2 sites up big time right in the middle of the day and had lost cpanel details on one. Fun times.
Found my password and had to delete from cpanel and all is good now. I’ve gone through and deleted all old shortcodes from the older version. I’m going to try and manually download and see if I can remove the duplicates before uploading to see if I can get it working.
