Copy Script Stopped Working

[sdsl]

I keep all my Dropbox files locally stored. I set up a special script to clone only that folder that has the local Dropbox files. It has worked many times in the past, creating a clone of that one folder on an external drive. I recently updated to 13.5 MacOS. Now when I run the script that worked fine in the past, it stops with this:

| 08:51:07 PM | Error | ***ERROR OCCURRED: bash: /Users/xxxx/Library/Application Support/SuperDuper!/Copy Scripts/Copy Dropbox folder.dset: Permission denied

I opened that script and resaved it, then tried again but got the same error.

Any idea why this might be happening or how to address it?

Thanks in advance!
