FTP connection keeps crashing since update 8.3 on mac os

[papillon-unix]

Cyberduke keeps displaying the "Broken pipe" error after I connect to FTP server.
It's very annoying and makes it unsuable. Didn't happen in version 8.2.3

I have the same problem with Cyberduck Version 8.3 running on a Mac Mini with macOS Catalina (Version 10.15.7). The FTP server is running on a Synology DS213j with OS DSM 6.2.4-25556 Update 5. I rolled back to Cyberduck Version 8.2.3 and I don't get the broken pipe error.
