Migrate off Dropbox - Error 100014

Dave

I have Boxcryptor 2.48.2029 on MacOS Sonoma 14.0. All works fine.
I'm trying to migrate away from Boxcryptor following the recent announcement. The steps are simply to copy from the boxcryptor directory and paste to another, non encrypted directory. When I attempt this I encounter error 100014 and the copy is aborted.

How do I migrate away from Boxcryptor? How do I copy all the files and decrypt them?

Thanks in Advance
