Let me know if you can reproduce after upgrading to macOS Tahoe 26.5.1.

As a workaround disable the user of the popover by entering in a Terminal.app window the preference

defaults write ch.sudo.cyberduck bookmark.window.popover false

I just installed Cyberduck for the first time and it keeps crashing when adding my first Bookmark. I am using Sequoia (cannot upgrade to Tahoe for compatibility reasons). Does that mean Cyberduck only supports MacOS Tahoe and above going forward?
It does say "macOS 10.13 or later on Intel (64bit) or Apple M1 required." on the download page.

We aim to support macOS 10.13 or later.

Any news on fixing this ? Quite unusable currently on macOS Version 26.5.2 (25F84)
