STEPS TO REPRODUCE 1. have an unmountable device in the places panel, e.g. an external HDD 2. make sure it is unmounted initially, or unmount it manually 3. right-click the item in the places panel for the unmounted device, and select "Open in New Window" OBSERVED RESULT A new window opens with the Home folder EXPECTED RESULT A new window opens with the folder of the selected device, optionally asking for any permissions to mount it. SOFTWARE/OS VERSIONS KDE Frameworks Version: 5.73.0 Qt Version: 5.15.0 ADDITIONAL INFORMATION I assume this is a bug and not intended, because both selecting "Open in New Tab" as well as simply left-clicking the places item mounts the device before it opens after asking for permission.
