Settings search (quick bar) opens as blank/empty box — HA 2026.4.1

The problem: When I click the magnifying glass in Settings (or press Ctrl+K), the quick bar dialog opens but the box is completely empty — no search field, no results, nothing. Just a blank dark box. Closing and reopening it doesn’t help.

What I’ve confirmed:

  • Reproducible in both Chrome and Microsoft Edge, so it’s not a browser or cache issue
  • HA itself is running fine — automations, entities, everything else works normally
  • Three frontend resources loaded via HACS/custom: Bambu Lab cards, Battery State Card, Mushroom — all load successfully (verified the JS files return 200)
  • No relevant errors in the HA Core logs
  • HA version 2026.4.1, HAOS 17.2

What I haven’t pinned down: I’m not certain exactly when it started — I don’t use the quick bar very often, so I can’t tie it to a specific change.

What I’m looking for: Anyone seen this before? Is there a known fix, or a way to force the frontend to rebuild/reload the quick bar component without a full reinstall?

It is a bug for which a fix PR has already been merged and should be in the next update (due yesterday).
