Tested on Wayland and it also happens.

I can't get the crash on dolphin 24.11.70, however, the settings field just turns empty instead of getting the current folder.

On Dolphin 24.08.0 (Frameworks 6.5.0, QT 6.7.2) still doesn't work, that button can't copy the current location and just empties the field, but at least not it only gives an error message about this without crashing. You can still change the default location imputing the location manually.

Should be now fixed with https://invent.kde.org/system/dolphin/-/merge_requests/823
