Comment (by yla):

 I have tried to replicate the issue with different file sizes and
 protocols but was not successful unfortunately. As long as I'm not able to
 replicate it the only way to find the cause would be to create a heap dump
 of the Cyberduck process. Not sure how technical you are but the steps
 would as follows:
 * install
 /OpenJDK13U-jdk_x64_mac_hotspot_13.0.2_8.pkg OpenJDK 13 - JDK] version (if
 not yet available on your system)
 jmap -dump:file=cyberduck-dump.hprof [PID of Cyberduck process]
 * provide a link to the dump file

 The dump file could be quite large. Let me know if you want me to share a
 link where you can drop the file.
