Fyi no issues were identified in testing and the updated Polkit packages are scheduled to go out in the next sync (I haven't heard about it being delayed so I assume this should happen shortly).
Once the sync happens please run sudo eopkg up
in a terminal and once the update completes reboot your computer and if you're a Plasma user you should see admin prompts start working again.
Edit: the sync happened, updated polkit is live.
