Comment (by ianfiretoys):

 I can confirm this issue on windows 10 with a newly updated 8.0.0, all
 servers using .ppks now fail to authenticate.

 ssh logins to those servers with the same key still work, and actually
 show the cyberduck attempts as failed logins on entry to bash

 can also confirm that the auth dialog also unsets the saved .ppk location
 every time i try again.

 have had to swap to filezilla for now, without an easy way to roll back
 cyberduck.

 If it helps narrow anything down my .ppk is stored in a google drive
 folder, and I've recently updated to the new google drive desktop app that
 does handle files differently.
