I am having the same issue, when I try and edit the header settings home assistant resets and all progress is lost.

Also when adding text into any field home assistant, instead of text being entered the bubble card editor closes.

This problem started after updating to Home Assistant Core 2025.3.0. Reverting to 2025.2.5 has fixed this for me.

The same problem after updating to Home Assistant Core 2025.3.0. My interface freezes when adding or editing any climate card. I noticed that this issue only occurs when using a vertical or horizontal stack. If the Bubble cards are added separately, everything works correctly.

Getting this too but only on my button card for my fan.

(And I see a problem in the temperature-heatmap-card too.)

Same here whith horizontal stack cards with bubble card insight. When I’m trying to modify a bubble card in a horizontal stack card, the browser crashes (tried with 2 browsers and the companion app on Android 15 - clicking on “2” in the red circle).

This applies only to existing cards, new cards generated after upgrading to new HA core are not affected.

Editing in YAML still works.

Bubble card 2.4.0 and HA Core 2025.3.0

Same problem here. Adding a sub-button only when the bubble-card is within a vertical-stack. When the bubble-card is not contained within a vertical-stack the editor works fine.
