FreeBSD 14.2 with KDE Plasma 5.27 on a virtual machine (VMware).
After installing Dooble (pkg install dooble) double-clicking on ANY file or shortcut on the desktop opens Dooble instead of the intended file or application. Dooble fetches that file and behaves like downloading the file from the web. As the result, the file is simply copied onto the desktop. The only way to restore the desktop functionality is to remove Dooble completely.
