Describe the issue you are experiencing

From time to time (inconsistently, maybe when it loads from cache?) I lost temporarily the views (tabs) of my dashboards: Only the first tab appears. The situation is similar to Developer tools: in this case neither the first tab appears, so there is no tabs ( so none of the yaml, states, services, etc are available) The situation is the same in the mobile companion app and in desktop browser too.

The only workaround to kill the app! and restart it, or fully re-load the page in the browser (ctrl+F5).

Describe the behavior you expected

tabs should be always visible.

Thank you for your suggestion. Fortunatelly? the safe mode solved it. As of now, I'm really out of hints, what component do this behaviour. I've tried to disable my custom components one by one (without deleting the cache unfortunatelly) but it doesn't popped out where the root cause is.

Hello, Just for the record: I've disabled alll the integrations and hacs addons systematically, and it does not solved the problem. Once upon a time I've (re-)discovered the resources page of the lovelace dashboards, where there was a manually added tv remote editor .js file from a source of the devil's coat. :D - I've added it years ago, and totally forget it. This integration was not used by any cards, but it was loaded....

Cheers,
