This was reported for duplicating particle systems, then using F9 to enable the 'Duplicate Settings' option (see T83317). In this case, the operator gets the particle_system from (buttons) context and if none can get found will duplicate all settings instead. The reason why none gets found here is that buttons_context() doesnt have a valid path when called from F9/SCREEN_OT_redo_last, path is cleared when global undo does a file-read which clears the path (see lib_link_workspace_layout_restore). It can be recomputed though to be valid even from redo_last (at least when in the Properties Editor). This was likely causing other operators (relying on buttons context) from the Properties Editor to fail as well.
